Authors: Xiuan Sui , Zhiyuan Wang , Shikun Tong , Yukun Guo , Jianbo Zhang
Published: October 2023

In the process of deepwater oil and gas development, hydrate formation and scale formation are easy to occur, and in serious cases, flow barriers will occur and threaten platform safety. A large amount of ethylene glycol and scale inhibitor is usually injected to ensure the safety of wellbore flow. However, due to the limited number of tree chemical pipelines, the joint injection of ethylene glycol and scale inhibitor is usually adopted. The inhibition efficiency of ethylene glycol and anti-scale agent on hydrate and scale was studied by single and compound evaluation experiments. In this paper, four kinds of high temperature anti-scale agents were selected based on Environmental conditions of the selected gas well, and compatibility evaluation experiments were carried out in combination with hydrate inhibitors to study the interaction between anti-scale agents and hydrate inhibitors. The experimental results show that PESA has high anti-scaling efficiency with MA/AA under the selected gas well conditions. But the hydrate conversion of MA/AA in the presence of ethylene glycol is low, and MA/AA has better scale prevention efficiency than PESA. Therefore, MA/AA has good compounding property with ethylene glycol and is suitable for the co-injection scheme of anti-scale agents and ethylene glycol.

This study had been performed to map the lateral and vertical heterogeneity of carbonate reservoir, using the newly acquired Ocean Bottom Node (OBN) data. Joint PP-PS pre-stack inversion has been performed to delineate the facies distribution and associated properties such as porosity and clay volume. This study greatly enhanced the depositional understanding of the area and helped to identify the in-fill well drilling and near-field exploration opportunities and provided attributes to update the existing reservoir model.
Practical Application of 3D Dubins Curve Method in Directional Well Trajectory Planning
Authors: Liu Haoge , Gjersvik Tor Berge , Faanes Audun
Published: October 2023

This paper introduces the practical application of 3D Dubins curve in directional well trajectory planning to handle more complex downhole conditions such as consecutive targets and various constraints in the underground formation. To handle consecutive targets in a direction well, we can simply treat the whole trajectory as a combination of multiple 3D Dubins curves with the undetermined drilling directions at the targets as additional optimization variables. As for the formation constraints, practical drilling may require the well trajectory to avoid certain areas or/and control the wellbore inclination in some layers to maintain wellbore stability. To handle such a problem, we can adjust the depth of kickoff point(KOP) or use a more complex trajectory structure with more curved sections rather than a simple trajectory structure with at most two curved sections (build-up & drop or two build-ups). The optimal trajectory generated by our method is the shortest smooth path satisfying all given constraints, besides, it has a fixed curvature in the curved section so that the tool face angle does not need to change so frequently during drilling. Our method was adopted by the NTNU Drillbotics team to design the optimal trajectory for consecutive targets, contributing to the NTNU championship in the 2022 SPE Drillbotics Competition. The advantages of our method in the complex application scenarios mentioned above are demonstrated in the case studies with comparison to a previously published result and real field data provided by Equinor.
A Deep Learning Framework to Forecast Spatial-Temporal Dynamics of CO2 Mineralization in Reactive Rocks
Authors: Tariq Zeeshan , Yan Bicheng , Sun Shuyu
Published: October 2023

Reactive rocks, such as basalt, are composed of a variety of minerals, with pyroxene, olivine, and plagioclase feldspar being among the predominant minerals. When exposed to carbon dioxide (CO2)-charged waters, these rocks can undergo a series of reactions, leading to the formation of stable carbonates. These carbonates can store carbon for thousands of years, contributing to climate change mitigation. To better understand the interplay between CO2 and brine in these reactive formations, numerical simulations are a very useful tool. However, simulating fluid flow in these reservoirs can pose significant computational challenges. The inherent reactivity of various minerals complicates the modeling process, leading to computationally expensive simulations. Therefore, the objective of this study is to develop a deep-learning workflow that can predict the changes in CO2 mineralization over time and space in saline aquifers, offering a more efficient approach compared to traditional physics-based simulations. To achieve this, a numerical simulation model was created to replicate the CO2 injection process in saline aquifers. The model was then sampled using the Latin-Hypercube method, considering various parameters related to petrophysics, geology, reservoir, and decision-making. These samples generated a comprehensive training dataset of approximately 700 simulation cases, forming the basis for training the UNet model, a type of convolutional neural network. The UNet models were trained, incorporating information on reservoir properties, well characteristics, and time, enabling the prediction of mineral precipitation at different spatial and temporal scales. During the training process, the root-mean-squared error (RMSE) was used as the loss function to prevent overfitting. Evaluation of the trained UNet model was performed using three error metrics: the normalized root mean square (NRMSE), mean absolute percentage error (MAPE), and the coefficient of determination (R2). The model achieved an R2 value of 0.998 for training and 0.991 for testing, indicating its accuracy in predicting the evolution of mineral concentrations over time and space. The MAPE for all mappings was approximately 5%, demonstrating the effectiveness of the trained model. In terms of computational efficiency, the UNet model’s prediction CPU time per case was remarkably fast, averaging only 0.2 seconds. This is significantly faster compared to the time required by the physics-based reservoir simulator, which took 21600 seconds per case. Thus, the proposed method not only provides accurate predictions comparable to physics-based models but also offers substantial computational time savings. The deep learning models developed in this study offer a computationally faster alternative to traditional numerical simulators for assessing mineralization trapping in geological carbon storage (GCS) projects, specifically concerning the mineral trapping mechanism.

Published: October 2023

The objective of the industrial case study is to address the challenge of efficiently managing end-of-life offshore assets while meeting established ESG targets. The offshore industry uses substantial amounts of steel, and current practices for handling these assets are often not transparent, leading to criticism for unsustainable and non-compliant scrapping procedures. The presented approach combines engineering and technical data from offshore assets with decommissioning best practices and digital and Al technologies to ensure a transparent and ESG-compliant approach to scrapping. This will provide auditable evidence of ESG compliance and is expected to address the challenge of managing end-of-life offshore assetswhile providing sustainable metals alternatives for heavy industry.

The use of Life Cycle Assessment (LCA) requires asset owners to demonstrate compliance with net zero targets, which is mainly impacted by the main material groups, such as steel. Recycled steel maintains its strength properties and if produced using electric arc furnaces and transported efficiently emissions can be minimized. The implemented solution offers a transparent, reliable, and ESG-optimized approach for scrapping assets. Each step in the process, from cutting to transportation to the metals furnace, can be tracked and audited, ensuring the end-product can be classified as ‘green’ steel. This steel can be used by asset owners to construct new vessels or facilities or can be sold to other users, creating a true circular economy where a significant amount of embodied carbon can be recycled and made net zero.

The use of advanced digital technologies in the offshore industry's scrapping and recycling process allows for a more transparent and sustainable approach. The procedure includes verification of environmental, social, and governance (ESG) parameters and information on carbon emissions, enabling the selection of the most environmentally friendly approach. This can provide transparency and stability in sourcing, ensure ESG compliance, and result in competitive pricing. Integrating the use of recycled metals, which has significantly lower emissions compared to non-recycled metals, can further decrease resource consumption and emissions while increasing the value of recycled by-products. Under this industrial study, up to 4.3 tons of CO2 can be saved for each ton of recycled stainless-steel scrap utilized. Furthermore, the breakdown of emissions in terms of handling, transportation and operations are illustrated in depth with validated emission factors.

The solution can be expanded to cover a variety of materials and assets, both offshore and onshore, to give asset owners peace of mind regarding their ESG responsibilities in the scrapping and construction value chain. This will provide a smooth, transparent, and efficient turnkey solution.
Corrosion Study of a Trunk Line of Western Offshore of India
Authors: Talukdar Maushumi Kakoti , Bareja Simran , Saini Arzoo
Published: October 2023

The Oil & Gas produced in one of the western offshore fields are carried through long distance pipelines to the onshore units, where they are processed for marketing. A number of leakages were reported in the Oil pipeline at different locations. It was commissioned in 2005 and the first leakage was observed in 2016 near the platform from where it is originating, and there after subsequent leakages were observed in 2018, 2022 and 2023. On analyzing the internal environment of the pipeline, the probable contributing factors were deduced. The water cut in the pipeline was reported as 1.5%, which shows the internal system remains oil wetted. The software study revealed the flow regime as transient. The microbial data shows the presence of SRB in the range of 102 per ml. As given in the leakage history, the leak location is primarily the butt weld in majority incidences with initial 26 kms of the pipeline. The bathymetry shows that there is sag and undulations in the segment of frequent leakage zone. As per thickness reduction data, there is severe metal loss in the nearby region of the leakages. The temperature profile shows that the temperature is in the range of 40-50°C in the leaked portions of the pipeline. This temperature range works best for bacteria to flourish and enhance their activity substantially4. It is also observed that, the H2S concentration is approximately 1500 ppm at the onshore end of the pipeline. However, the concentration of H2S at the platform ends of lines that are connected to this main pipeline was reported to be within 400 ppm. In another study carried out at our institute in 2009 it was observed that at that time period the H2S concentration of this pipeline was around 300 ppm at the onshore end. These facts also support the proliferation of SRBs at the sag bends of the pipeline, whose presence has resulted in substantial increase in H2S in the pipeline. However, in the segment where there are no significant undulations, no leakage is reported till date. MTM survey also shows the thickness reduction in this segment is mostly in less severe zone. As the pipeline samples were not available for analysis but with all the supporting data it may be concluded that the leakages were mainly due to microbial induced corrosion (MIC). Adequate recommendations are deliberated in the technical paper. In the Gas line, the CO2 is present in range of 2.65 - 2.81 mole % while H2S concentration remains in range of 97 - 105 ppm. It is CO2 dominated system. The SRB count in the line is 105 which is very high. The high content of Iron in the Gas line shows that the corrosion is taking place and the line is susceptible to leakages. This study will help in deciding the future strategy of the lines.

Authors: R. Sherin D. , R. Linda S. , A. Akhila
Published: October 2023

In the relentless quest for effective treatments against SARS-CoV-2, extensive exploration of potential inhibitors has been underway. In this study, we present an integrated approach combining machine learning and in silico screening to identify promising inhibitors for the SARS-CoV-2 receptor-binding domain (RBD). We harnessed a dataset of Vina scores for 988 gingerol substructures, employing Random Forest (RF) regression as the optimal model to predict Vina scores accurately (R² = 0.77). Virtual screening, both through RF predictions and PyRx, consistently highlighted 14 molecules with inhibitory potential. Pharmacokinetic evaluation, aided by the Bioavailability Radar and a BOILED-Egg simulation, further refined the selection of four leads-G4, G5, G11 and G13 with human intestinal absorption, out of which the P-gp non substrate G13 (PubChem CID: 135196841) can be act as a promising candidate. Molecular docking, molecular dynamics simulations, and Density Functional Theory (DFT) calculations validated the stability and interactions of this compound with the SARS-CoV-2 RBD. Our study offers a streamlined methodology for identifying potential inhibitor, paving the way for further experimental validation.

Authors: Zakhary Ibrahim , Alani Hasanain , Firouzi Tara , Ditmyer Macia , Ahmad Maha
Published: October 2023

Background: A mandatory preclinical suture laboratory was implemented as part of the Oral Surgery course where students were trained and allowed to practice various suturing techniques on cadavers under direct supervision of an oral surgeon. The primary purpose of this study was to evaluate the students’ perception of the effectiveness of this lab experience in preparing them for performing sutures during their oral surgery rotations.
Methods: The second year dental students during 2014/2015 participated in a preclinical suturing lab.
Suturing techniques were demonstrated to students by an oral surgeon, immediately followed by practice sessions. Students received formative feedback and the opportunity to repeat any procedure to ensure they were subsequently able to perform the techniques properly. Following their Oral Surgery rotation, students were asked to complete an electronic survey about their preclinical simulation lab experience. They rated how important they felt this simulation lab was to performing suturing correctly, whether the simulation lab was properly aligned in the curriculum, the course design and implementation of the simulation lab, time allocated for the session and practice, whether the didactic portion complement the preclinical lab portion, and overall impression of the simulation lab experience.
Results: Students who received the preclinical simulation lab suture training reported that they were more comfortable and confident in performing suturing
techniques in their surgical rotations. Students also reported that it would be helpful having more practice sessions available.
Conclusion: The laboratory was effective in preparing the pre-doctoral students at the right time of the program to perform various suture techniques prior to starting oral surgery rotations.
Subnanometric Platinum–Germanium Clusters Break the Activity–Stability Tradeoff in Propane Dehydrogenation
Authors: Furukawa Shinya , Nakaya Yuki
Published: October 2023

Propane dehydrogenation has been a key technology with great industrial promise for meeting the growing global demand for propylene. Although much effort has been devoted to developing ideal catalysts that demonstrate high catalytic activity, selectivity, and durability at the same time, there have been no reports on the achievement of this goal due to a tradeoff between activity and selectivity/stability. Herein, we report that subnanometric Pt–Ge alloy clusters encapsulated in pure silica MFI zeolite break the activity–stability tradeoff in propane dehydrogenation. We also discovered that MnOx could act as an efficient co-catalyst to reach the full potential of Pt–Ge alloy clusters by preventing hydrogen poisoning. The MnOx-PtGe@MFI catalyst exhibited exceptionally high catalytic activity, selectivity, and durability in the absence of co-fed hydrogen at 600°C, exceeding those of other reported catalysts. Mechanistic study revealed that the combination of subnano-downsizing and Ge doping to Pt was the origin of the exceptional performance, and anti-sintering ability provided by the zeolite cage was not a key to the great enhancement of catalyst stability.
Komplexe Wörter zwischen Konstrukt und Konstruktion: Neuere gebrauchsbasierte Ansätze und ihre Implikationen für die Wortbildung
Authors: Hartmann Stefan
Published: October 2023

Die Wortbildung spielte in der Konstruktionsgrammatik lange eine untergeordnete Rolle. Spätestens seit Booijs (2010) „Construction Morphology“ hat sich dies jedoch geändert, und gerade in der diachronen Betrachtung der deutschen Wortbildung ist die Konstruktionsgrammatik zu einem wichtigen theoretischen Framework geworden. Zugleich gab es im Bereich der Konstruktionsgrammatik und der gebrauchsbasierten Linguistik im Allgemeinen interessante theoretische Weiterentwicklungen, die beispielsweise die Frage nach der Struktur des „Konstruktikons“ oder den theoretischen und kognitiven Status von Konstruktionen betreffen. In diesem programmatischen Beitrag diskutiere ich die theoretischen und forschungspraktischen Implikationen, die diese neuen Entwicklungen für das Gebiet der Wortbildung haben, und greife eine Reihe offener Fragen auf.
Zweifelhafte Morphologie in Konstruktionen
Authors: Audring Jenny
Published: October 2023

In der Syntax hat die Konstruktionsgrammatik einem ‘Aschenputtel’ der Linguistik zu neuen Ehren verholfen: den Idiomen. Für die Morphologie gilt ähnliches, denn ein konstruktionistischer Ansatz ermöglicht das Aufwerten unproduktiver, selbst marginaler Muster, die für generativistische Ansätze von geringem Interesse sind. Die vorliegende Arbeit bespricht eine Reihe von exemplarischen Fällen zweifelhafter Morphologie und zeigt, welche Fragen, Herausforderungen und Lösungen sich aus einer konstruktionsbasierten Analyse ergeben. Mit einem Bogen zurück zu den produktiven Mustern wird für eine inklusive Theorie plädiert, die sowohl den möglichen, als auch den bereits existierenden Wörtern Rechnung trägt.
Paradigmatic relations in Construction Morphology: the case of Dutch Noun+Verb compounds
Authors: Booij Geert
Published: October 2023

The formal and semantic properties of Noun+Verb compounds in Dutch can be accounted for by means of paradigmatically related word-constructional schemas. We can form verbal compounds with an infinitival head from nominal compounds with a deverbal head noun, for instance boekbespreken ‘to book-review’, derived from boekbespreking ’book review’ through substitution of ‑ing by ‑en. The paradigmatically related constructions of verbal compounds with an infinitival head and nominal compounds with a deverbal head thus constitute a paradigm for word formation. The paradigmatic origin of verbal compounds makes the rare use of finite forms of these compounds understandable. The form of nominalizations for Noun+Verb compounds provides additional evidence for the paradigmatic origin of these verbal compounds. The analysis proposed lends support to morphological frameworks in which paradigmatic relations between words play a crucial role, such as Construction Morphology.

Prioritizing the Components of the Disaster Resilient System Using DEMATEL and ANP for Urban Areas
Authors: Sarmadia Hajar , Aghababaei Siavash
Published: October 2023

Although many research studies have been performed on vulnerability assessment and hazard mitigation, it is extremely hard for communities to cope with disasters appropriately. There are many uncertainties and unanticipated issues in disasters; therefore, coping with disasters and emergencies is not as simple and easy as mitigation and preparedness activities. The concept of disaster resilience has been described as a method to overcome unforeseen problems. This paper aims to discover and prioritize dimensions and components of Disaster Resilient System (DRS) in urban areas using Delphi, Decision Making Trial and Evaluation Laboratory (DEMATEL) and Analytic Network Process (ANP). Numerous frameworks and models have been used to define relevant dimensions and components of DRS based on the Delphi method. The relationship between the components has been determined using DEMATEL. Finally, obtained data has been applied to ANP to define a conceptual model and to obtain a weighted supermatrix for prioritizing the main components of DRS. The results of the study have shown that a Comprehensive Emergency Plan (CEP) is the most important component for earthquake resilience in urban areas.
Cultural divergence in Sujata Bhatt’s poem “Search for My Tongue”
Authors: Ahamed Nachiya S.
Published: October 2023

This research paper deals with the culture object in Sujata Bhatt’s poem “SEARCH FOR MY TONGUE”. Sujatha Bhatt was born  in Gujarat and immigrated to the United States. The persons who admire poetry are aware of what’s going around the world which gives muse to write poems, and sometimes they write poem that connect those to their culture. The present study depicts the life of immigrants who experience the specific tension. Like the speaker Sujata Bhatt, they try to adjust their life in a new country, without forgetting where they come from(native). Sujata also explores how immigrants must often negotiate between  supposedly irreconcilable cultural identities, their own, and that of dominant culture which they belong. It also slides on how the dominant culture can threaten to erode an immigrant’s identity. People migrate primarily for social and  economical reasons that causes a wide gap between the culture and traditions they follow. Being  an Indian, the poet tells her trauma of adapting herself to a new culture. “Search for my tongue” is a poem by Sujata Bhatt, here, the poet includes English and Gujarati lines. Bhatt herself as an immigrant explores how hard it is to adapt to a new culture. The pressure of assimilation and the association between the language and identity fades the native culture. The  poet tells her second language overtakes her mother language, the loss of  native language would be a loss of her heritage and sense of self- identity which can diminish the culture. Towards the finish of the poem, she witnesses herself, that her primary language had a quality to tie a bunch on her second, going to be her local language appears to have revived her. The euphoric finish of the poem reaffirms the association between language, personality, and self articulation proposing that by utilizing her native language, the speaker has recovered a piece of herself from migration and absorption. She likewise proposes other immigrants, to build up another far off character that incorporates both of their social and cultural experiences.

Creating automatic passwords and patterns based on image processing from back hand wrinkles
Authors: Mariasamy A
Published: October 2023

Passwords, Patterns and Finger prints are a ubiquitous part of the present age. They are the keys to unlock our online profiles, bank accounts, mobile phones, iPad, opening money Box (safe) which is hosted across a plethora of websites and other electronic devices. With each of our profiles necessitating a separate password, it is not uncommon for people to need up to 50 passwords. Recent events have now seen hundreds to millions of passwords leaked in online, more than one hundred million LinkedIn logins and tens of millions of Twitter logins were made available on the darknet. This paper aims at proposing a novel objective approach which utilizes wrinkles on the back four fingers of the human to create patterns or passwords automatically using randomization by extracting the four fingers back wrinkles using sensors then merging all four fingers’ wrinkles together and make the system to create pattern or password without known by the user or any human beings. Each and every time the same wrinkles group is detected it creates and changes new passwords. This cannot be known to anyone. This can be done through image enhancement and morphologic methods through wrinkle retrieval.  We identify the pixels of the image of wrinkles and label them as letters for each and every pixel of a particular finger wrinkles and give decimal values from the ASCII table. We merge all four finger tables and start creating randomized patterns using Boolean Expression. The methodology is explained below.
Effect of hypothyroidism on ovarian reserve status in Iraqi women:
hormonal study
Authors: M Abbas Eman , Saleh Basil O , Aljuboori Omar M
Published: October 2023

Background: Hypothyroidism is a clinical syndrome prevalent in
women, even those of reproductive age. Ovarian reserve can be defined as the
number and quality of follicles in the ovary at any given time. Evaluation of ovarian reserve is recommended for patients at risk of decreased ovarian reserve. Objective: This study aims to evaluate the effect of hypothyroidism on ovarian reserve
in Iraqi women by hormonal measurements of serum anti-mullerian hormones
AMH, FSH, and LH. Subjects and methods: This case–control study was carried
out at the Department of Biochemistry, College of Medicine, University of Baghdad, in collaboration with Endocrinology and Diabetes Clinic, Baghdad Teaching
Hospital, and National Center for Teaching Laboratories, Medical City, during the
period from November 2021 to March 2022. This study involved 88 women, age
range (20-40 years). Fifty-one of them [Group I (GI)] had primary hypothyroidism
and were diagnosed by an endocrinologist based on clinical analysis and thyroid
function tests, including serum TSH, T4 and T3. Patients with symptoms and signs
suggestive of hypothyroidism and elevated TSH with T4 less than the reference
level were considered overt hypothyroidism.
While patients with elevated TSH with standard T4 and T3 were considered subclinical hypothyroidism 1
, serum thyroid peroxidase antibody (TPOAb) was used
to differentiate hypothyroidism patients with Hashimoto`s disease 2
. Thirty-seven
of the included women were healthy and served as a control group and referred to
group II (GII). Results: The mean (±SD) value of serum AMH of hypothyroidism
women was significantly lower than that of controls (p < 0.0001). However, the
mean value of AMH did not differ significantly between women who had overt
and subclinical hypothyroidism, regular and irregular menstrual cycle, well and
poorly controlled thyroid status, and who had positive and negative anti-TPO. The
mean (±SD) value of serum LH of hypothyroidism women was significantly higher
than that of the control group (p < 0.004), while that of FSH did not differ significantly. Serum TSH levels positively correlated with LH levels (r=0.3, p 0.03). In
addition, BMI values were significantly positively correlated with FSH levels (r=
0.3, p 0.04). Conclusions: This study suggested the need for serum measurement
of AMH in women suffering from hypothyroidism.

Published: October 2023

Proteus mirabilis (P mirabilis) is the major pathogenic bacteria, an etiological
agent of wound infections, particularly skin wound infections. Infection of wounds
is the cause of morbidity and mortality on a universal scale. Different pathogens
infecting wounds can colonize and multiply in the wounds, damaging the host
tissue. This work aimed to determine biofilm formation, detect some virulence
factors, and estimate the action of different antimicrobial agents i.e., antibiotics
and probiotics Lactobacillus spp. P mirabilis was collected from different specimens of humans. Virulence factors of P mirabilis, especially atfA,rsbA, and mrpA,
were observed in the isolates of P mirabilis through PCR technique. Isolates P
mirabilis virulence factors were detected in more than 90%. The rate of susceptibility was 35 (94.6%) for cefoxitin, 29 (78.4%) for tobramycin, 22 (59.5%) for
imipenem, followed by amikacin [16 (43.2%)], cefotaxime [11(29.7%)], ciprofloxacin [9 (24.3%)], ampicillin [1 (2.7%)]. As well as, different virulence biofilm
genes related to the susceptibility for different antimicrobial agents, whether antibiotics or probiotics, such as rsbA [21 (100%)], atfA [20 (95.2%)] and mprA [19
(90.5%)]. Furthermore, probiotic lactobacilli spp. Such as Lactobacillus acidophilus and Lactobacillus casei shirota demonstrated high sensitivity against pathogens compared with antibiotics in different methods, such as agar spot (22-26 mm)
and well diffusion (8-13 mm). In conclusion, P mirabilis demonstrated a high level
of susceptibility to antibiotics against cefoxitin, tobramycin and imipenem and
high resistance to ampicillin and others. Also, Lactobacillus spp. Demonstrated
high sensitivity against pathogens compared with antibiotics.

Published: October 2023

Background

TikTok is a popular social media platform that allows users to create and share content through short videos. It has become a place for everyday users, especially Generation Z users, to share experiences about their reproductive health. Owing to its growing popularity and easy accessibility, TikTok can help raise awareness for reproductive health issues as well as help destigmatize these conversations.

Objective

We aimed to identify and understand the visual, audio, and written components of content that TikTok users create about their reproductive health experiences.

Methods

A sampling framework was implemented to narrow down the analytic data set. The top 6 videos from each targeted hashtag (eg, #BirthControl, #MyBodyMyChoice, and #LoveYourself) were extracted biweekly for 16 weeks (July-November 2020). During data collection, we noted video characteristics such as captioning, music, likes, and cited sources. Qualitative content analysis was performed on the extracted videos.

Results

The top videos in each hashtag were consistent over time; for example, only 11 videos appeared in the top 6 category for #BirthControl throughout the data collection. Most videos fell into 2 primary categories: personal experiences and informational content. Among the personal experiences, people shared stories (eg, intrauterine device removal experiences), crafts (eg, painting their pill case), or humor (eg, celebrations of the arrival of their period). Dancing and demonstrations were commonly used in informational content.

Conclusions

TikTok is used to share messages on myriad reproductive health topics. Understanding users’ exposure provides important insights into their beliefs and knowledge of sexual and reproductive health. The study findings can be used to generate valuable information for teenagers and young adults, their health care providers, and their communities. Producing health messages that are both meaningful and accessible will contribute to the cocreation of critical health information for professional and personal use.

UNSTRUCTURED

This viewpoint aims to provide a comprehensive understanding of vaping from various perspectives that contribute to the invention, development, spread, and consequences of e-cigarette products and vaping. Our analysis showed that the specific characteristics of e-cigarette products as well as marketing strategies, especially social media marketing, fostered the spread of vaping and the subsequent effects on human health and toxicity. We analyzed the components of e-cigarette devices and e-liquids, including the latest variants whose impacts were often overlooked. The different forms of nicotine, including salts and freebase nicotine, tobacco-derived nicotine, tobacco-free nicotine, and cooling agents (WS3 and WS23), have brought more choices for vapers along with more ways for e-cigarette manufacturers to advertise false understandings and present a greater threat to vapers’ health. Our work emphasized the products of brands that have gained significant influence recently, which are contributing to severe public health issues. On the other hand, we also discussed in detail the toxicity of e-liquid components and proposed a toxicity mechanism. We also noticed that nicotine and other chemicals in e-liquids promote each other’s negative effects through the oxidative stress and inflammatory nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway, a mechanism leading to pulmonary symptoms and addiction. The impact of government regulations on the products themselves, including flavor bans or regulations, has been limited. Therefore, we proposed further interventions or harm reduction strategies from a public health perspective.
Modern neuroimaging criteria for diagnosing multiple sclerosis in children
Authors: Palamarchuk Y.O.
Published: October 2023

The article presents a clinical case of multiple sclerosis (MS) in a 10-year-old female patient, the use of one of the advanced magnetic resonance imaging (MRI) techniques, namely proton magnetic resonance spectroscopy (1H-MRS), in the diagnosis of MS. MRI is an integral part of the diagnostic algorithm for patients with multiple sclerosis according to the McDonald criteria, which were last updated in 2017. In addition, MRI allows assessing the course of the disease, serving as a criterion for confirming the aggravation of the pathological process. Although the McDonald criteria are applied in adults, they are also used to diagnose MS in children, and MS in children has its own particularities. The McDonald criteria include traditional (conventional) MRI sequences: T2-weighted images, T1-weighted images, post-contrast T1-weighted images. With the rapid development of MRI, cutting-edge (advanced) MRI techniques have emerged that allow for a better understanding of changes in the brain matter in MS: brain volumetry, magnetization transfer imaging, cortical imaging, diffusion tensor imaging, 1H-MRS, susceptibility-weighted imaging. In particular, 1H-MRS allows us to assess the degree of white matter integrity by detecting increased resonance of myelin breakdown metabolites. The studies have shown that changes in MS have their own specificity, but there is no consensus on this issue. Currently, there are no agreed guidelines that would include advanced MRI techniques, but we believe they will allow us to better understand the course of MS and to predict the development of the disease. This approach will improve the management of MS in both adults and children and quality of their life.
Advancements in surgical management of glioblastoma: current trends and promising future directions

Published: October 2023

Glioblastoma (GBM) is the most common and malignant adult brain tumor. Despite substantial study and surgical advancements, the prognosis remains poor, demanding ongoing research of the current trends and potential surgical therapy. This abstract summarizes GBM surgical developments and future directions. GBM is treated with maximal safe resection, adjuvant radiation, and chemotherapy. Tumor penetration into eloquent brain areas often complicates surgical excision. Functional brain mapping and intraoperative imaging have increase safe resection. Awake craniotomy and intraoperative fluorescence-guided surgery may help remove more tumor. GBM surgery now incorporates molecular and genetic data. Molecular profiling helps discover mutations and genetic changes for tailored treatment. Immunotherapies and targeted therapies have the potential to enhance treatment outcomes for patients diagnosed with GBM. Precision medicine, which involves tailoring cancer treatments to each patient’s unique characteristics, is expected to play a pivotal role in future research endeavors. Nanotechnology and drug delivery devices offer the opportunity to optimize the delivery of anti-tumor drugs, potentially improving their efficacy. Artificial intelligence and machine learning in preoperative planning and intraoperative decision-making should improve surgical results. Current trends in GBM surgery include maximizing safe resection using advanced mapping and imaging techniques, incorporating molecular information for personalized treatment, and investigating targeted therapies and immunotherapies. The future of GBM surgery lies in the integration of precision medicine, nanotechnology, and artificial intelligence. By adopting these innovations, the surgical management of GBM may experience significant improvements, leading to better patient outcomes and an increase in life quality.

As discussões e perspectivas concernentes à tópica da curiosidade assumiram importância e interesse no pensamento hespérico na medida em que, ao se encontrarem imbricadas com o desejo de conhecer, pulsão humana pela investigação, acabaram por transbordar do campo da ética para outras regiões do conhecimento como para a epistemologia, a psicologia e a filologia, desvelando, assim, inegável potência interdisciplinar e pluralidade cultural.

De nossa parte, agregada à tradicional pertinência do tema, constatamos, após levantamento preliminar da literatura crítica, do quão escassamente tal matéria (nas áreas e períodos aqui reunidos) se faz representar nos periódicos brasileiros. Sobretudo, os artigos que compõe o presente Dossiê da Revista Territórios & Fronteiras refletem e questionam acerca dos aspectos históricos, filosóficos e culturais que são mobilizados na polissemia de sentidos e nas ambiguidades valorativas da curiosidade e do curioso em seus múltiplos desdobramentos. Pretendem, pois, proporcionar fecundo contato com a literatura consolidada sobre o tema, e, indo além, oferecer interpretações sobre as variadas faces da curiosidade e do curioso em distintos cenários.
repercussões internacionais do genocídio das populações indígenas em Putumayo, no Peru, e as reações da Santa Sé
Authors: Marin Jérri Roberto
Published: October 2023

O trabalho procurou investigar a repercussão no Brasil e as reações da Santa Sé diante dos crimes cometidos contra as populações indígenas pela empresa Peruvian Amazon Rubber Company em Putumayo, no Peru. As denúncias e acusações envolveram a Inglaterra e vários países latino-americanos, que foram pressionados a proteger tais populações. O papa Pio X reagiu ao enviar um delegado apostólico e ao publicar a encíclica Lacrimabili Statu Indorum. O objetivo da Igreja Católica era assegurar sua presença entre os indígenas, ampliar a presença na sociedade e o controle religioso em detrimento do pensamento laico e das religiões concorrentes.
