Mining Oil and Gas Law: The Geopolitical Vicissitudes of the Extractive Industries
Authors: Parsalaw Benjamin J.
Published: November 2024

The oil and gas industry has been critically acclaimed as one of the most prominent and lucrative business sectors of the 21st century. From a perspicacious viewpoint, the oil and gas sector is lauded for generating revenue, engendering foreign direct investment, and stimulating innovation via state-of-the-art technology. This paper draws emphasis on the fact that resource extraction must comply with the concept of sustainable development through mitigating efforts. Collectively, most of the pungent criticisms that deprecate the prospects of oil and gas mining are commonly reduced to human rights violations and environmental dilapidations. The inauspicious domino effect of the oil and gas industry not only transcends but presents a more alarming challenge as opposed to the immediate human rights and environmental impacts. Geopolitical tensions fueled by national interests have occasioned numerous forms of conflicts at the international level. In what has been termed “the resource-curse,” countries rich in natural resources such as oil and gas are customarily prone to political and economic volatility. The “Dutch-disease,” on the other hand represents a corroboration of the stagnation of other economic sectors as a result of neglect due to overreliance and dependence on oil and gas. The paper further asserts that, at this juncture, international law and relations have been severely predisposed by the oil and gas industry through foreign policy. As a foreign policy tool, oil and gas mining prescribes international alliances and the national interests of key stakeholders. In turn, foreign policy decisions related to oil and gas mining, have led to copious disputes and economic sanctions with geopolitical implications and motivations. This paper posits that in addition to human rights and environmental concerns, there are intrinsic challenges such as the resources-curse and Dutch-disease that form an integral part of the deleterious reputation tainting the oil and gas industry. While acknowledging the benefits, this paper accentuates that the extreme risk and reward aspect necessitates a comprehensive understanding of the multifaceted challenges inherent in the legal framework regulating the oil and gas mining industry

Published: November 2024

Lower technology nodes or Ultra Deep Sub-micron (UDSM) used in today’s System on-chip (SoC) yield high performance and are faster when compared to the Deep Sub-micron (DSM) technology nodes. The challenges faced by a designer have increased multi-fold in SoC design with the technology node evolution. The designs that are trending these days are Hard Macro (HM) based designs. The entire block is divided in the sub- HMs or hierarchical blocks. The sub-HM layout shapes are decided during the partitioning of the top-level block. Each of the hierarchical blocks is implemented separately and the sub-HMs are integrated at the top level to reduce the huge run-time and to reduce the burden of improving the PPA. The processes involved in Physical Design (PD) are interlinked and the effect of the previous process can be seen in the subsequent stages. CTS is implemented using Flexible-H-tree (FHT) with Multiple tap point structure. Experimental results on an industrial design having more than a million instances show that the implementation of the proposed clock tree structure comprising of FHT with Multitap point CTS (DB2), in the design, shows huge improvement in terms of timing and clock metrics when compared to the conventional CTS (DB1). A reduction of 40.47% and 63.9% is seen in terms of hold WNS and hold TNS respectively from DB1 to DB2. The NFE is reduced by 27.33% from DB1 to DB2. DB2 has a clock latency of 1.073 ns which is 27% lesser than that of DB1. Global Skew is reduced by 15.48% and local skew by 20%. Innovus tool is used for the implementation of the design.

Internal and External Determinants of Banking Stock Performance: Evidence From The Indonesia Stock Exchange
Authors: Syahid Aliah Muthiah , Pitriana Ida , Lestari Henny Setyo
Published: November 2024

This study examines the factors influencing stock performance in banking institutions listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. A quantitative approach using panel data regression is applied to assess the impact of internal financial metrics—such as Earningss per Share (EPS), Dividend per Share (DPS), Price-to-Earningss Ratio (P/E), and Book Value per Share (BVPS)—as well as external macroeconomic variables, including inflation, Gross Domestic Product (GDP), and bank size, on Market Price per Share (MPS). The study employs the random-effect model, along with statistical tests such as Chow, Hausman, and Lagrange Multiplier, to determine the most suitable regression model. The results reveal that EPS, BVPS, and bank size have significant positive impacts on MPS, indicating that higher profitability, strong intrinsic equity value, and larger institutional size are associated with better stock performance. In contrast, DPS, P/E, inflation, and GDP show no significant influence, suggesting that investors in the banking sector focus more on other aspects, such as EPS, BVPS, and bank size rather than the amount of dividends distributed, share price compared to profitability, inflation, and GDP. These findings offer practical implications for bank management to enhance financial performance and attract investments by focusing on improving profitability and equity growth. Additionally, this study serves as a valuable reference for investors in developing stock selection strategies by emphasizing the importance of strong fundamentals. Furthermore, the research identifies limitations in existing variables in capturing stock volatility and recommends future studies to expand the scope by incorporating additional market dynamics and longer observation periods.

Digitalization as the key to better medical care - better work through more technology? A literature review on the development opportunities for the German care sector
Authors:   MATE- Kaposvar Campus, Kaposvar, Hungary, Kremer Oliver , Franke Romy ,   Independent researcher
Published: November 2024

The basic idea behind the German healthcare system is based on the idea that comparatively many young individuals look after relatively few old members of society in a kind of fictitious intergenerational contract. This assumption has been outdated since 1972, when the number of deaths exceeded the number of newborns and society therefore began to shrink. The resulting demographic change led to a gradual increase in costs in the German healthcare system, which was accompanied by a gradual increase in demand for healthcare professionals. Shrinking societies are a phenomenon that can be observed across a broad front, particularly in western industrialized countries. In view of the overall economic conditions, the question inevitably arises as to the future performance of German medical care and, above all, in the further consideration of the care sector. The possibilities offered by digitalization, particularly in the field of telemedicine, are therefore suitable in the medium to long term for counteracting the gradual deterioration of the situation in nursing care. In the future, telemedicine will be an elementary component of medical care for the German population. The results of this paper show the positive long-term effects of telemedicine for this specific economic sector and outline the corresponding building blocks for the desired German healthcare innovation.

: This study aims to investigate the effect of the implementation of international maritime law and the quality of ship crews on the prevention of coastal environmental pollution with ship safety as a mediating variable in the Bintan Island area. With a focus on the issues of the implementation of maritime regulations that are not yet optimal and the variability of the quality of ship crews, this study uses a quantitative descriptive method approach with a sample of 160 ship crews in Bintan Island. The standard theory in takingThe samples used in this study were obtained using the Nonprobability Sampling technique with Saturated Sampling. Data were collected through a questionnaire that measured the variables of the application of international maritime law, the quality of the ship's crew, ship safety, and prevention of coastal environmental pollution. Data analysis was carried out using Structural Equation Modeling Partial Least Squares (SEM-PLS) to evaluate the relationship between variables. The results of the study indicate that the application of international maritime law has a significant effect on ship safety and prevention of coastal environmental pollution. In addition, the quality of the ship's crew also affects ship safety and pollution prevention efforts. Ship safety has been shown to play a significant role as a mediator in the relationship between the application of international maritime law andquality of ship crews with prevention of coastal environmental pollution. The discussion of these findings indicates that increasing the implementation of international maritime law and improving the quality of ship crews can improve ship safety and reduce environmental pollution. Ship safety plays a crucial role in mediating this relationship. This study concludes that stricter policies and effective training for ship crews will contribute to the protection of the coastal environment in Bintan Island. The implications of these results emphasize the importance of implementing better maritime policies and improving the competence of ship crews to achieve optimal results in preventing coastal environmental pollution.

An Evaluation of Nigerian Women's Political Engagement in Nigeria
Authors: Ajose Osigbodi
Published: November 2024

Nigerian women continue to face severe under- representation in elected and appointed positions, while comprising half of the nation's population and exerting considerable influence in the voting process, particularly in organising and promoting the process at the lowest levels of society. Political hurdles, socio-cultural issues such as patriarchy, religious dogma, anti-egalitarian behaviours, and conventional views of women in politics and socioeconomic hurdles such as low income, a lack of resources, electoral processes and political party structures, have all been identified as barriers to women's political engagement as such, the objective of this study is to evaluate Nigerian women's political engagement in Nigeria quantitatively. The study used quantitative research methods where the questionnaire was administered to 150 respondents. The result of the findings shows that low levels of female appointments to the national parliament are significantly related to women's political voting eligibility, according to the research at t = 3.125, df = 148, and p = .002, which implies that voting eligibility of women is a significantly positive predator of appointment of women in politics. It further shows that both men and women in Nigerian politics have been the primary sponsors of politics aimed at increasing women's representation in government. The study concluded that it would take a while for women to get to that point where women will be significantly participating in Nigerian politics because women face so many problems in public places. In the same way, Nigerian women need to make their own culture that goes against the deeply rooted traditions that say what women should or shouldn't do or be, especially in an African setting and recommended that the government should look at the current federal constitution, policy-making, and regulatory framework, to see if any regulations might make it harder for women to participate equally, such as rules that require a lot of signatures to register as a candidate or high deposits of money that can be unfair to women candidates. As a result, laws that give women and men equivalent rights and responsibilities should be passed.
Increased Prevalence of Schizophrenia Disorder, a Case of Rwinkwavu District Hospital, RWANDA
Authors: Ndikubwimana John Peter , B. Silali Mourice
Published: November 2024

Schizophrenia is a chronic mental disorder impacting millions globally, with its prevalence influenced by genetic, environmental, socioeconomic, and socio- cultural factors. Approximately 1% of the world population is affected, with higher rates observed in urban areas. This study aims to assess the prevalence of schizophrenia among patients visiting Rwinkwavu District Hospital, with a specific focus on identifying its occurrence within this population. The significance of this study lies in its potential to inform healthcare providers and policymakers on the critical rates of schizophrenia, supporting the development of targeted interventions to mitigate its impact. A descriptive cross-sectional study design with a mixed-methods approach was employed, analyzing patient files, registers, and electronic medical records (EMRs) of 312 patients diagnosed with mental disorders between June 2023 and June 2024. Quantitative data were analyzed using SPSS version 27 with descriptive and inferential statistics, while qualitative data were gathered through key informant interviews and focus groups. Findings reveal a schizophrenia prevalence of 34% within the study area, predominantly affecting adults aged 18-40. The study underscores the need for enhanced community mental health empowerment programs to address schizophrenia, which constitutes 34% of mental health disorders treated in Kayonza District, as observed in Rwinkwavu District Hospital.
The Study of Jet Formation Mechanism in Fermi Blazars
Authors: Xie Shangchun , Ouyang Zhihao , Wu Jingyu , Xiao Hubing , Zhang Shaohua , Chen Yongyun , Luo Zhijian , Fan Junhui
Published: November 2024

The origin of jet launching mainly comes from two mechanisms: the Blandford–Znajek (BZ) mechanism and the Blandford–Payne (BP) mechanism. However, it is in debate which one is dominating in blazars. In this work, we used a sample of 937 Fermi blazars to study the jet formation mechanism. We studied the correlation between the jet power and the accretion rate, as well as the comparison between jet power estimated by spectral energy distribution (SED) fitting and that estimated by theoretical formula and radio flux density. Our results suggest that there is no correlation between jet power estimated by SED fitting and the accretion rate for BL Lacertaes (BL Lacs), while a positive and weak correlation exists for flat spectrum radio quasars (FSRQs). Meanwhile, to confirm whether the BP and BZ mechanism is sufficient to launch the jet for FSRQs and BL Lacs, we compare the theoretical jet power with that estimated by SED fitting, as well as that by radio emission. We found that the jet power for most of the two subclasses estimated by SED fitting cannot be explained by either the BP or BZ mechanism. While the jet power for most FSRQs estimated by radio flux density can be explained by the BP mechanism, and most BL Lacs can be explained by the BZ mechanism. We also found that FSRQs have higher accretion rates than BL Lacs, implying different accretion disks around their central black holes: FSRQs typically have standard disks, while BL Lacs usually have advection-dominated accretion flow disks.
Instability in Supernova Fallback Disks and Its Effect on the Formation of Ultralong Period Pulsars
Authors: Yang Hao-Ran , Li Xiang-Dong , Gao Shi-Jie , Xu Kun
Published: November 2024

Several pulsars with unusually long periods were discovered recently, comprising a potential population of ultralong period pulsars (ULPPs). The origin of their long periodicity is not well understood, but may be related to magnetars spun down by surrounding fallback disks. While there are few systematic investigations on the fallback-disk-assisted evolution of magnetars, instability in the disk has received little attention, which determines the lifetime of the disk. In this work we simulate the evolution of the magnetic field, spin period, and magnetic inclination angle of magnetars with a supernova fallback disk. We find that a thermal viscous instability in the disk could significantly affect the formation of ULPPs. Our simulation results also reveal that a large fraction of ULPPs seem to be nearly aligned and orthogonal rotators. This might help place ULPPs above the death line in the pulse period–period derivative plane. However, some extra mechanisms seem to be required to account for the radio emission of ULPPs.
Nonlinear Perturbations and Weak Shock Waves in Isentropic Atmospheres
Authors: Faran Tamar , Matzner Christopher D. , Quataert Eliot
Published: November 2024

Acoustic perturbations to stellar envelopes can lead to the formation of weak shock waves via nonlinear wave steepening. Close to the stellar surface, the weak shock wave increases in strength and can potentially lead to the expulsion of part of the stellar envelope. While accurate analytic solutions to the fluid equations exist in the limits of low-amplitude waves or strong shocks, connecting these phases generally requires simulations. We address this problem using the fact that the plane-parallel Euler equations, in the presence of a constant gravitational field, admit exact Riemann invariants when the flow is isentropic. We obtain exact solutions for acoustic perturbations and show that after they steepen into shock waves, Whitham’s approximation can be used to solve for the shock’s dynamics in the weak to moderately strong regimes, using a simple ordinary differential equation. Numerical simulations show that our analytic shock approximation is accurate up to moderate (∼few–15) Mach numbers, where the accuracy increases with the adiabatic index.

Obstructive sleep apnea (OSA) detection using single-lead electrocardiograms (ECGs) has advanced significantly with the integration of artificial intelligence (AI). This review explores how AI enhances feature extraction and machine learning algorithms to improve OSA detection. The RR interval in electrocardiographic data is particularly valued for its ease of identification and low error rate. We review a range of machine learning and deep learning techniques employed in OSA detection. This review offers insights into developing single-lead ECG-based OSA detection systems by analyzing database availability, feature extraction methods, and machine learning approaches.
Le Châtillonnais, contester et administrer un espace en marge (IXe-XIIIe siècles)
Authors: Vergine Thomas
Published: November 2024

La frontière comme une stricte ligne est un concept récent qui remonte au XVIIe siècle. Au Moyen Âge, c’est davantage la notion de limite qui semble opérante pour définir cet espace frontalier, sorte de bordure qui circonscrit un territoire plus ou moins cohérent, mais qui ne constitue pourtant pas nécessairement une frontière au sens strict. Le Châtillonnais, aujourd’hui région naturelle formant la partie septentrionale de la Côte-d’Or, constitue à partir du IXe siècle un enjeu territorial majeur situé en marge des deux principautés régionales, le temporel de l’évêque de Langres et le duché de Bourgogne en formation. Si par définition la frontière se situe aux confins d’un territoire, elle n’en retient pas moins l’intérêt des pouvoirs en place qui tentent par divers moyens de la contrôler. Face à cette nécessité de dominer l’espace, les acteurs du pouvoir assurent le contrôle de ces marges par la possession des principaux pôles d’autorité régionaux. Ceux-ci, souvent des châteaux ou des agglomérations issues de ces derniers, ne forment pas une ligne infranchissable mais constituent un maillage sur l’ensemble du territoire, en des endroits stratégiques, pour affirmer la présence et le contrôle d’un seigneur sur celui-ci. La maîtrise d’un territoire passe alors par la maîtrise de ces pôles qui sont le siège d’une autorité sur un hinterland plus ou moins vaste. Cependant, le Châtillonnais ne correspond initialement à aucune circonscription administrative. C’est une région qui s’est progressivement constituée entre le IXe et le XIIIe siècles, à partir du Duesmois et d’une portion du Lassois, sous la conduite des ducs de Bourgogne qui n’ont eu de cesse de contester l’autorité épiscopale dans ce territoire marginal conduisant finalement, à l’aube du XIVe siècle, à la fixation d’une frontière pérenne entre Bourgogne et Champagne encore fonctionnelle de nos jours.

Lawrence and the “homeless soul”
Authors: Costin Jane
Published: November 2024

Beginning by exploring ideas of “home,” this article shows how Lawrence’s reaction to Zennor in Cornwall establishes that, at least for a while, this was a place Lawrence regarded as home. In examining what contributes to feelings of “home,” it will make reference to “The Cathedral” chapter in The Rainbow where Will’s soul is depicted as being “homeless” because it is challenged by ideas outside of the church. It will then contrast this with Lawrence’s reaction to such matters. It will explain how a particular aspect of Zennor during the time Lawrence lived there were its connections to Aleister Crowley and occult ideas - things that were outside the church and that questioned Lawrence’s thinking. It will then look at Lawrence’s interest in the occult around this period, which will lead to the suggestion that, for Lawrence, a place that made his soul feel “homeless” was a place that he felt “at home.”
La loi de 1905 n’aura pas lieu. Tome III : L’Église catholique « légale malgré elle » (1905-1908)
Authors: Baubérot Jean
Published: November 2024

Le 9 décembre 1905, la loi de séparation des Églises et de l’État est promulguée. Si les deux premiers tomes de cette fresque historique ont dévoilé les difficultés menant à cette étape cruciale, ce troisième volet montre à quel point promulgation et validation ne riment pas toujours. De nombreux prélats catholiques déclarent le 1er janvier 1906 « jour de deuil », date à partir de laquelle « Dieu n’existe plus ». Alors que les motifs d’inquiétude surgissent – la fin du « service public des cultes » et donc de leur financement par l’État, les inventaires des biens d’églises vécus comme une « spoliation » –, le pape choisit la résistance, condamnant successivement toutes les dispositions légales que l’État désire mettre en place pour l’exercice des cultes, et désavoue les évêques français. Le peuple, lui, semble avoir accepté la loi, les élections législatives de 1906 étant un nouveau succès pour la majorité sortante de gauche. Le recours à une histoire contrefactuelle (« ce qui serait arrivé si… ») montre comment des situations en apparence inextricables ont pu être dénouées par une stratégie d’esquive qui rend l’Église catholique « légale malgré elle ». Renouvelant une historiographie trop lisse, ce troisième tome donne à lire les efforts d’un trio politique éclatant – Georges Clemenceau, Jean Jaurès et Aristide Briand – pour éviter une « guerre religieuse » résultant d’une « victoire excessive », et permettre à la République d’obtenir une victoire durable car pacificatrice.
Bernard Manin et les ambivalences des démocraties antiques
Authors: Buffet Jules , Roux Nina
Published: November 2024

Les travaux de Bernard Manin sur le gouvernement représentatif ont profondément renouvelé l’étude des régimes politiques et de la démocratie en particulier. Par la comparaison des caractéristiques théoriques du tirage au sort et de l’élection, Manin montre que ces deux institutions, et en particulier l’élection, sont intrinsèquement à la fois démocratiques et aristocratiques. C’est donc l’ensemble des institutions et de la culture politique d’une société qu’il faut prendre en compte pour définir son régime politique. Ce dernier dépend toujours d’une série de choix institutionnels qui contribuent ensuite à façonner son fonctionnement. Les travaux de Bernard Manin permettent aux antiquisants de penser que, de même que le gouvernement représentatif, pensé à l’origine en opposition à la démocratie directe antique, peut déboucher sur des pratiques politiques plus ou moins démocratiques, de même ce n’est pas la présence ou l’absence de telle ou telle institution (assemblée, conseil, contrôle des magistrats…) qui détermine le caractère plus ou moins démocratique des cités grecques.
De la chambre à coucher à la chambre funèbre : Thomas Laqueur et l’Antiquité
Authors: Bérard Reine-Marie
Published: November 2024

Issu d’un séminaire envisageant l’influence réciproque des sciences de l’Antiquité et des sciences sociales dans l’historiographie du xixe au xxie siècle, cet article analyse l’usage des sources antiques dans l’œuvre de l’historien américain Thomas Laqueur (1945-), en particulier dans son premier et plus célèbre livre Making Sex: Body and Gender from the Greeks to Freud (1990) et l’intérêt de ce travail, en retour, pour les sciences de l’Antiquité. Après avoir présenté brièvement la thèse principale de l’ouvrage qui oppose un « modèle du sexe unique » (qui aurait caractérisé la représentation des concepts de sexe et de genre de l’Antiquité jusqu’au xviiie siècle) à un « modèle des deux sexes », qui serait né dans le sillage des Lumières et encore valable aujourd’hui, cette contribution présente un certain nombre de critiques de la lecture que Laqueur impose aux auteurs grecs antiques, notamment Galien, Hippocrate et Aristote. La seconde partie de l’article montre cependant l’intérêt des travaux de Laqueur pour renouveler l’approche théorique et pratique de l’archéologie funéraire, notamment autour de l’articulation des notions de sexe biologique (aujourd’hui employée pour désigner les données issues de l’étude anthropologique des squelettes) et de genre social des défunts (tel qu’il peut être perçu à partir des données de l’archéologie). Malgré une évolution vertueuse des pratiques marquée par des collaborations de plus en plus étroites entre archéologues et anthropologues, les travaux de Laqueur invitent à démonter les rouages d’une opposition plus complexe qu’elle ne semble pour proposer une nouvelle approche des notions de sexe et de genre en archéologie funéraire.
La mise en scène de l’Égypte ancienne dans la BD « Sur les terres d’Horus » Quand la fiction se joue des stéréotypes
Authors: Charron Alain , Triquet Éric
Published: November 2024

La série « Sur les terres d’Horus » se situe sous le règne de Ramsès II au xiiie siècle avant J.-C. et met en scène le Prince Khaemouaset, fils de pharaon et grand prêtre de Ptah à Memphis, la capitale économique du pays. Celui-ci est chargé par son père de résoudre des affaires qui pourraient gravement attenter au pouvoir royal. Au fil des intrigues imaginées par l’autrice Isabelle Dethan, des questions contemporaines sont abordées comme la place des femmes dans cette société ou encore le rapport aux croyances. Si la série mêle, dans un même scénario, fiction et faits scientifiques, la volonté de dépasser les stéréotypes liés au monde antique est ici manifeste. Le présent article est le fruit d’une rencontre entre un archéologue et un chercheur en sciences de l’information et de la communication. Il propose un regard croisé sur cet objet hybride et se fixe un double objectif : 1. repérer comment Isabelle Dethan s’appuie sur des stéréotypes habituels de l’Égypte antique pour s’assurer l’adhésion de ses lecteurs ; 2. à l’inverse, montrer comment, dans le même temps, elle les prend à revers, les interroge et parfois même les réfute, de façon à bousculer les certitudes de ses lecteurs.
Le site archéologique de Carthage, hier et aujourd’hui. À propos d’un livre récent d’Abdelmagid Ennabli
Authors: Jaïdi Houcine
Published: November 2024

L’ouvrage d’Abdelmagid Ennabli a été conçu d’abord comme étant une « topobibliographie » destinée à fournir toutes les références des publications relatives aux vestiges archéologiques du site de Carthage, datant de la période 1830-2016. Précédée d’un historique des recherches et organisée dans le cadre de secteurs dégagés à partir de la Carte Bordy publiée en 1906, la bibliographie est accompagnée d’une riche illustration et de commentaires qui la mettent en contexte et en précisent l’apport et/ou les limites. L’auteur, qui a longuement commenté les destructions, l’absence ou l’étendue de la mise en valeur et les ressorts de l’appropriation sous le Protectorat français et depuis l’indépendance du pays, a prêté une attention particulière aux réalisations de la Campagne UNESCO (1972-2001) dont il a été le coordinateur et qui ont fait profiter le site de nombreuses actions de sauvegarde, recherches, publications et valorisations remarquables malgré certains inachèvements. Mis en perspective par des publications parues au cours des deux dernières décennies, l’ouvrage, à la conception bien originale, se révèle être, malgré quelques réserves, d’un apport documentaire majeur et un instrument de travail désormais incontournable pour la connaissance de l’évolution des recherches archéologiques relatives au site de Carthage, de la réception de son héritage et de l’usage qui a été fait de son histoire au cours des deux derniers siècles ainsi que des problèmes qu’il continue à affronter.

Tuberous sclerosis with no cutaneous manifestations
Authors: Narang Gursharan Singh , Khurana Mandeep Singh , Charan Gopal Singh , Kaur Maninderjit
Published: November 2024

Tuberous sclerosis complex (TSC) is a neurocutaneous disorder caused by mutations in the TSC1 and TSC2 genes. The most common clinical symptom of TSC is seizures. Approximately one in 10,000–50,000 individuals are affected. A clinical investigation detects the popular facial nevus, seizures, and mental retardation in fewer than half of patients. The key tool for the diagnosis of this neurocutaneous syndrome is radiological imaging. Here, we report a rare case of tuberous sclerosis with mental retardation, seizures, attention-deficit hyperactivity disorder (ADHD), and cortical tubers on magnetic resonance imaging brain, but no cutaneous manifestation of the disease.
Robotic nephron-sparing surgery for a high-complexity renal carcinoma in an obese patient with chronic kidney disease Stage 4
Authors: Vallam Karthik Chandra , Lalityaswarna P. , Beesetty Bhaskara Rao
Published: November 2024

The approach to managing renal masses has significantly changed over time. Traditionally, nephrectomy was the standard treatment for both large and small tumors, but modern practices are more nuanced. Today, treatment strategies are tailored to each patient’s overall health, personal preferences, and specific tumor characteristics. In recent years, partial nephrectomy has become the standard of care whenever possible. However, this approach is not always feasible in complex renal tumors. Radical nephrectomy continues to be the preferred method for larger, complex tumors and those with aggressive growth patterns. The rise of minimally invasive procedures has empowered the surgeon to perform nephron-sparing partial nephrectomy in complex tumors too. We report the case of a 70-year-old obese patient with a complex left renal tumor and chronic kidney disease. The patient underwent robotic partial nephrectomy with clear margins and no deterioration of renal function which was of paramount importance in preventing progression to overt renal failure requiring dialysis.

Application value of high-pressure-resistant peripherally inserted central catheters in enhanced computer tomography of diabetic patients with malignant tumors
Authors: Zhang Li , Yan Hui-Feng
Published: November 2024

BACKGROUND

Individuals with diabetes mellitus have a higher risk of developing malignant tumors, and diagnosing these tumors can be challenging.

AIM

To confirm the benefits of using peripherally inserted central catheters (PICCs) in contrast-enhanced computerized tomography (CECT) for diagnostic imaging in diabetic patients with malignant tumors and to provide a research basis for follow-up research.

METHODS

This retrospective study analyzed 204 diabetic patients with malignancies treated at The Second Affiliated Hospital, Jiangxi Medical College, Nanchang University, from January 2024 to June 2024. The patients were divided into two groups: A control group (n = 102) with indwelling peripheral intravenous catheters and a research group (n = 102) with high-pressure-resistant PICC. The study compared baseline data, the incidence of iodine contrast extravasation during CECT, the incidence of adverse events (discomfort, redness and swelling at the puncture site, and blood oozing), imaging quality, nursing time, intubation success rate, number of venipuncture attempts, and catheter maintenance cost.

RESULTS

Male patients accounted for 51.96% in the control group and 55.88% in the research group; the average age was (59.68 ± 11.82) years in the control group and (61.41 ± 12.92) years in the research group; the proportions of lung cancer, colorectal cancer, and gastric cancer patients in the control group were 42.16%, 38.24%, and 19.61%, respectively, while those in the research group were 34.31%, 37.25%, and 28.43%, respectively. Except for the gender distribution, age, and cancer type mentioned above, other general information such as underlying diseases, puncture location, and long-term chemotherapy shows no significant differences as tested (P > 0.05). The results showed that the research group had significantly reduced incidence of iodine contrast extravasation (7 vs 1, P = 0.031), similar incidence of adverse events (11 vs 7, P = 0.324), reduced nursing time [(18.50 ± 2.68) minutes vs (13.26 ± 3.00) minutes, P = 0.000], fewer venipuncture attempts [(2.21 ± 0.78) times vs (1.49 ± 0.58) times, P = 0.000], lower catheter maintenance cost [(1251.79 ± 205.47) China yuan (CNY) vs (1019.25 ± 117.28) CNY, P = 0.000], increased intubation success rate (16.67% vs 58.82%, P = 0.000), and better imaging quality (85.29% vs 94.12%, P = 0.038).

CONCLUSION

High-pressure-resistant PICCs can lessen the physical burden of diabetic patients during nursing, reduce treatment costs, and improve the efficiency and quality of imaging for diagnosis malignant tumors.
