Crítica al liberalismo económico. Una respuesta desde la industria cultural y la cultura del rendimiento
Authors: Garrido Gerardo R.
Published: July 2024

Este artículo tuvo como objetivo el análisis del liberalismo económico y su influencia en la actividad política de los ciudadanos, considerando dos fuentes: i) la industria cultural, cuya noción explica cómo el ritmo industrial convierte a la persona en un ser instrumentalizado, alejándolo poco a poco de la crítica y la reflexión social mediante el consumo, la estandarización de la vida y el espectáculo; y ii) la cultura del rendimiento, en donde la sociedad premia la alta productividad , la eficiencia y eficacia. Se utilizó el método argumentativo, el analítico-comparativo y el crítico-analítico. Se utilizó la revisión bibliográfica para formular los principios del liberalismo económico, basándose en el texto: “Liberalismo”, de Juan Ramón Rallo. Para desarrollar la crítica se basó en los textos de: “Dialéctica de la Ilustración”, escrita por Theodor Adorno y Max Horkheimer; y en “La Sociedad del Cansancio”, escrita por Byung Chul-Han. Por medio del análisis se concluyó que las dinámicas del libre mercado tienen una influencia negativa en el interés y la actividad política de las personas.

Published: July 2024

Works of art are born from emotional impulses based on the worldview and interests of society that are passed down through generations. Fine art is related to the expression of beauty, entertainment, communication, skills, and hygiene. Fine art is an inseparable part of people's lives with various types that fulfill each individual's artistic taste. However, the era of technology and globalization has had an impact on the shift in art and cultural values. This research tries to analyze, explore the facts to what images and opinions occur on Aksera Surabaya's social media accounts. This research uses a constructivism criticism approach. The constructivism paradigm has the view that social life is not a natural reality, but a reality formed from the results of construction. This research uses the framing analysis method to find out and analyze the communication style and branding on Aksera Surabaya's social media. The results showed that Aksera Surabaya's social media did not maximize the existing features, such as Instagram Live, Reels music, and tags in Instagram posts.

Published: July 2024

Previous studies have shown that astragalus may inhibit lung cancer, but its anticancer components and molecular mechanisms have not been fully elucidated. The aim of this study was to identify the primary active components and targets of astragalus against lung cancer through a comprehensive search in authoritative databases. Subsequently, protein–protein interaction, gene ontology, Kyoto Encyclopedia of Genes and Genomes enrichment analyses, and correlation analysis of key targets with lung cancer were performed, and their binding activity was evaluated by molecular docking simulation. The main active components of astragalus against lung cancer were identified as jaranol, quercetin, kaempferol, isomucronulatol, isorhamnetin, methylnissolin, 3,9-di-O-methylnissolin, and 7-O-methylisomucronulatol, which involved seven key targets (CYP19A1, EGFR, SRC, PIK3CA, ABL1, CDK4, and CDK6) and PI3K/AKT-signaling pathway. Further results showed that kaempferol and quercetin had a high binding activity with CDK6 and methylnissolin with PIK3CA. Also, the overexpression of CDK6 and PIK3CA was associated with poor prognosis in lung cancer patients. This study has systematically elucidated the correlation between “astragalus-targets-signaling pathway-lung cancer”: kaempferol, methylkinisoline, and quercetin in astragalus may inhibit lung cancer through CDK6-PI3K/AKT-signaling pathway. These compounds are expected to be potential candidates for natural small-molecule anticancer drugs.

Published: July 2024

This study aimed toinvestigate the effect of baicalein on migration and invasion of human cutaneous squamous cell carcinoma A431 cells. A431 cells were incubated with baicalein with concentrations of 0 (control), 2, 4, 8, 16 and 32 μmol/L, respectively. The cell proliferation, apoptosis, migration, invasion and expressions of matrix metalloproteinse-2 (MMP-2), matrix metalloproteinse-9 (MMP-9) and vascular endothelial growth factor (VEGF) protein were detected. Results showed that, with 32 μmol/L baicalein and treatment for 72 h, the cell proliferation inhibition and apoptosis rates were the highest. With 32 μmol/L baicalein and treatment for 48 h, the cell migration and invasion inhibition rates were the highest, and the MMP-2, MMP-9 and VEGF protein expression levels were the lowest. In conclusion, baicalein can inhibit the proliferation of A431 cells, promote the apoptosis, and inhibit the invasion and metastasis. The mechanism may be related to its down-regulation of MMP-2, MMP-9 and VEGF expressions.

Correlates of Social Phobia among Undergraduate Students in Universities in Rivers State
Authors: Benson Blessing Owere , Kemjika Obi. Greg
Published: July 2024

The prevailing level of social anxiety especially in Rivers State is on the increase and this has led to a number of issues including low self-esteem, poor emotional intelligence, poor communication, low performance in oral examination, quizzes and debates. Again, the lack of awareness on the part of the parents resulting in poor parental support not only heightens social anxiety among students but makes the problem complex. Hence, the current study focused on correlates of social phobia among undergraduates in Universities in Rivers State. Correlational research design was used in the study. The population consisted of 84,000 undergraduates in three Universities in Rivers State. A sample of 509 respondents drawn using multi-stage sampling procedure used in the study. Four instruments including Emotional Intelligence Scale (EIS) Students Self-concept Questionnaire (SSCQ) as the Social Anxiety Scale (SAS) were used for the study. The reliability coefficient values were 0.81, 0.70, 0.71, and 0.79 respectively. Simple regression was used to analize the data collected. Result showed that EI (p=0.034<0.05), self-concept (p=0.039<0.05) and self-efficacy (p=0.043<0.05) all had significant relationship with social phobia. Based on this, it was recommended among others that counselors, parent and teachers should help build good emotions skills in the students. They should not make them to be afraid neither should they make them to be timid as this to a great extent has significant influence on the extent which they can create social relationship.

Authors: Abdulrazaq Tumba Tijani , Gambo Nasamu , Lamino Hauwa Abubakar , Nwoye May Ifeoma
Published: July 2024

Fiscal policies play a pivotal role in navigating economic recovery, particularly amidst financial and pandemic crises in African countries. This study evaluates the influence of the unemployment rate, government expenditure, and government capital expenditure on economic recovery in selected African nations. The objectives include assessing the significance of these factors in the context of crises and testing hypotheses regarding their relationships with economic recovery. Drawing from the Keynesian economic theory and Structural Adjustment Theory, the study provides a theoretical framework for understanding the efficacy of fiscal interventions. Using a deductive approach and multiple regression analysis, data from ten African countries spanning from 1981 to 2023 are analyzed. The findings underscore the critical role of the unemployment rate and government capital expenditure in driving economic recovery, while general government expenditure shows minimal direct impact. Policymakers are urged to focus on targeted investments in capital projects and initiatives to address unemployment rates, thereby fostering sustainable economic growth and resilience.

Published: July 2024

For the present research, an attempt was made to study the influence of magnetic field and thermophoresis on an existing mathematical model. The impacts made by both magnetic parameter and thermophoresis over the nanofluids flux as well as the characteristics of transfer of heat are studied and analyzed by using a suitable numerical method (Runge- Kutta- Fehlberg method together with shooting technique) in maple2020. Also the effects of some emerging physical parameters on the profiles of momentum and temperature have been studied and analyzed in tables and graphs. Two solutions are obtainable if the free stream and the plate moves conversely to each other. At the end it was found that the Nusselt number is mostly an increasing function, whereas, the momentum and the temperature fluctuates with different parameters.

Application of Social Space as a Tool for Physical Planning: Case Study of Mymensingh Town
Authors: Akhtaruzzaman Ahmed , Kabir Md Ahsanul
Published: July 2024

Space has a social dimension. Social space consists of physical space and mental space. Physical and mental perspectives are only able to achieve partial description or cross-sections of space. The general approach of physical planning is concentrated only on physical dimension of space. Most city planners deal with essentially static concepts with land use maps and plans they prepare. They tend to view the city as a static arrangement of physical objects which lacks in mental space. Again, mind is spatially oriented. Hence, there is a gap between the ways our cities have been built and the way people perceive them. Above all, neither the plan nor their underlying studies have successfully depicted the city as a social process operating in space. In the course of time, every section and part of the city takes on something of the character and qualities of its inhabitants. In current (urban) planning process, space is dealt to offer on facilities and services people require to have a better life. It is ignored to explore how they perceive their surrounding and every day’s space domain. This paper explores ‘social space’ as a planning tool and examines its potential application in the physical planning process.
Propounding “Structured Innovative Thinking Techniques for Social Sciences Research”: Why this can be a Game Changer in Social Sciences Research
Authors: Mandavili Sujay Rao
Published: July 2024

The starting point of this paper is a very brief overview and review of the concepts and postulates of our previously published paper “Baking innovative and creative thinking techniques into scientific method: Towards innovative and creative techniques as an intrinsic part of scientific method for higher scientific and research output”, which was published by us in the early part of 2024. We then also review and summarize various existing innovative and creative research techniques such as the six hat thinking techniques and lateral thinking techniques, and then proceed to overview our approach which was called the “Structured innovative thinking techniques for Social Sciences Research”. This approach is suitably expanded upon and forms the logical basis of this entire paper. There are multiple points of interface with our earlier papers to varying degrees, and these include our papers on twenty-first century intellectualism, the eight pillars of social science research methods and techniques, and the theory of paradoxes, which we have published in the recent past, albeit to a much smaller extent and degree. We believe that this paper will add enormous value to science in general, and catapult scientific activity to a much higher league. It is as such in tandem with our broader globalization of science movement.
Fuzzy time series clustering using autoencoders neural network
Authors: Ibebuchi Chibuike Chiedozie
Published: July 2024

This study presents a novel approach that employs autoencoders (AE)—an artificial neural network—for the nonlinear transformation of time series to a compact latent space for efficient fuzzy clustering. The method was tested on atmospheric sea level pressure (SLP) data towards fuzzy clustering of atmospheric circulation types (CTs). CTs are a group of dates with a similar recurrent SLP spatial pattern. The analysis aimed to explore the effectiveness of AE in producing and improving the characterization of known CTs (i.e., recurrent SLP patterns) derived from traditional linear models like principal component analysis (PCA). After applying both PCA and AE for the linear and nonlinear transformation of the SLP time series, respectively, followed by a fuzzy clustering of the daily SLP time series from each technique, the resulting CTs generated by each method were compared to assess consistency. The findings reveal consistency between the SLP spatial patterns from the two methods, with 58% of the patterns showing congruence matches greater than 0.94. However, when examining the correctly classified dates (i.e., the true positives) using a threshold of 0.8 for the congruence coefficient between the spatial composite map representing the CT and the dates grouped under the CT, AE outperformed PCA with an average improvement of 29.2%. Hence, given AE's flexibility and capacity to model complex nonlinear relationships, this study suggests that AE could be a potent tool for enhancing fuzzy time series clustering, given its capability to facilitate the correct identification of dates when a given CT occurred and assigning the dates to the associated CT.

De la fête galante à la conversation entre les genres : la place de Philip Mercier dans l’évolution de l’art du portrait en Angleterre
Authors: Alayrac-Fielding Vanessa
Published: July 2024

Le peintre Philip Mercier, issu d’une famille française huguenote,
quitta Berlin pour s’installer à Londres en 1716, après avoir effectué
son grand tour en Italie et en France. Son œuvre anglaise, très
prolifique, reflète une grande variété générique et stylistique,
comprenant des scènes champêtres et des fêtes galantes dans le style
d’Antoine Watteau, qu’il imita pour lancer sa carrière londonienne,
des peintures de conversation, des portraits et des « fancy
pictures ». Cet article propose d’explorer la carrière de Philip
Mercier en Angleterre à travers l’évolution de son style, depuis sa
pratique artistique ancrée dans le sillage de Watteau jusqu’à
l’élaboration des « fancy pictures ». Il s’agira de montrer que la
production artistique de Mercier s’inscrivit dans le contexte
économique et culturel de la première moitié du XVIIIe siècle et entra en résonance avec les courants
esthétiques et l’épistémologie lockienne de cette période.
Thomas Gainsborough’s “Carelessness”: Portraiture, Technique and Individuality
Authors: Gould Sarah
Published: July 2024

This article delves into Thomas Gainsborough’s distinctive painting
style, characterised by fluid, expressive brushwork, and how it was
perceived by his contemporaries as a form of “carelessness.” By
revealing the mechanics of his craft, Gainsborough simultaneously
inscribed his work within the prestigious lineage of the Old Masters,
while also redefining the concepts of portraiture and identity. The
article explores the historical lineage of his technique, noting that
Gainsborough’s “odd scratches,” as described by Joshua Reynolds, are
reminiscent of a painting tradition identified by the art historian
Nicola Suthor as “bravura.” Yet it also
addresses a specific cultural context by discussing the perceived
femininity of Gainsborough’s style and its significant role in shaping
the evolving concept of individuality during the late 18th century. The article argues that Gainsborough’s
deliberate “studied carelessness” contributed to the new regime of
individuality prevalent in the age of sensibility. Furthermore, it
examines the influence of Gainsborough’s technique in shaping a
national art school in Britain and his impact on late Victorian
artists, emphasising the dual nature of his style as both an
expression of individual genius and a reflection of broader trends in
British art.
From Heroic to Romantic: Reynolds’s Captain the Honourable Augustus Keppel (1753) and its Legacy
Authors: Ibata Hélène
Published: July 2024

Joshua Reynolds’s second portrait of Augustus Keppel (1752-53) –
which masterfully blended portrait and history painting, as well as
heroic and pre-Romantic mood – contributed to the construction of a
semantically fluid pictorial identity, a type of dominant masculinity
that could assume a multiplicity of roles, not only in the context of
Britain’s imperial expansion, but also in an age of social and
intellectual transition. This paper examines its influence on naval
portraiture, focusing on John Hamilton Mortimer’s group portrait of
Captain James Cook, Sir Joseph Banks, Lord Sandwich,
Dr Daniel Solander and Dr John Hawkesworth (1771) as well as
depictions of Horatio Nelson. Further transformations of the paradigm
are analyzed, with an emphasis on its ability to depict new types of
national celebrities in its Romantic adaptations, as suggested by
portraits of Lord Byron, to conclude with John Everett Millais’s
ultimate revisitation of the iconography of the naval portrait in his
1874 North-West Passage.
Sociability and portraiture from William Hogarth to Thomas Lawrence
Authors: Ogée Frédéric
Published: July 2024

The period between 1730-1830 saw the rise of an English school of
art, much later than the other schools on the European continent.
English portrait painters played a crucial part in this evolution by
deploying the art of portraiture in infinite variations, in search of
a veracity and an intimacy whose contours and peculiarities they
tirelessly strove to capture and render. Indeed, they radically
transformed their chosen pictorial genre by transcribing onto canvas
the new conceptions and perceptions of the individual which had
emerged in the Age of Enlightenment. Sensitive to the new universalist
values associated with the notions of identity, individuality and
sociability, the British portraitists set out to represent the variety
and diversity of human beings, moving away from ancient types and
models to focus on the particular, singular, circumstantial
personalities of the models. In this essay I try to present the
narrative of this remarkable blossoming, focussing on the works of a
series of exceptional artists—William Hogarth, Joshua Reynolds, Thomas
Gainsborough, Thomas Lawrence—whose works provide us with a remarkable
visual chronicle of the evolutions of men, women and children in this
rich moment in European history.
Cinquante ans depuis la révolution des œillets
Authors: Secco Lincoln , Coggiola Osvaldo
Published: July 2024

La révolution des Œillets a été portugaise et européenne. Les enjeux qui l’ont motivée étaient communs aux sociétés européennes d’après-guerre : décolonisation, démocratie politique (lutte contre l’autoritarisme et les dictatures), intensification des affrontements de classes. Au Portugal, ces différentes tensions convergent et explosent rapidement à l’occasion de la crise des forces armées. Ses acteurs politiques, du MFA à l’extrême gauche, sont contraints d’improviser des réponses politiques à des événements qui les surprennent souvent. En Europe, comme dans le monde, cette révolution a été considérée comme la continuation de la vague amorcée en 1968, de l’est à l’ouest. Son résultat impliqua l’ensemble des forces politiques, à commencer par les États-Unis et les courants de gauche internationaux. Cet article rend compte, d’une manière synthétique, du panorama complexe qui a marqué un processus qui, avec la fin de la « dictature des colonels » en Grèce et la démocratisation espagnole, a conditionné deux des grands enjeux du dernier quart du 20e siècle, l’émergence de l’Union européenne et la vague néolibérale.
Perspectives sur le double pouvoir dans la révolution au Portugal, de Nicos Poulantzas à Raquel Varela
Authors: Sotiris Panagiotis
Published: July 2024

Cet article revisite les dynamiques du double pouvoir durant la révolution portugaise pour interroger leur pertinence dans les débats contemporains. Il analyse tout d’abord les tensions qui traversent le texte de Nicos Poulantzas, The Crisis of the Dictatorships [La Crise des dictatures, Portugal, Grèce, Espagne], en s’appuyant également sur d’autres travaux de cette période issus de la gauche révolutionnaire. Il s’intéresse ensuite à A People’s History of the Portuguese Revolution [Un peuple en révolution. Portugal, 1974-1975] de Raquel Varela, qui met en évidence la dynamique du double pouvoir au sein de la révolution portugaise sans tomber dans les écueils des approches antérieures. Enfin, il formule quelques conclusions provisoires sur la façon de penser le double pouvoir d’un point de vue stratégique.

OPTIMIZED U-NET SEGMENTATION MODEL AND DEEP MAXOUT CLASSIFIER FOR BRAIN TUMOR CLASSIFICATION
Authors: Thomas Subha , Sudarmani R.
Published: July 2024

The most serious nervous system ailment, a brain tumor impairs one’s health seriously and ultimately results in death. MRI, one of the most frequently used medical imaging modalities for brain tumors, has emerged as the main diagnostic system for the treatment and study of brain tumors. It was challenging to segment and classify the many kinds of brain tumors. The swarm intelligence approach has the potential to more efficiently and effectively tackle a number of issues. Therefore, this work develops a novel model for the classification of brain tumors that includes various phases. Primarily, the input image is preprocessed via the proposed median filtering that aids in removing noises. Subsequently, segmentation is done via optimal U-Net. For precise segmentation, the weights are tuned optimally by battle royale optimization with the Bernoulli randomization (BROBR) algorithm. Then, features like the proposed local Gabor XOR pattern (PLGXP), texton features, gray level co-occurrence matrix (GLCM), and correlation features are extracted. Finally, BTC is done using a deep maxout network (DMO) that provides the final output on the absence or presence of a brain tumor.

Published: July 2024

Human corporeality enters bioethics as its own content and fundamental problem. In fact, “bioethics” is a composite term that links together bios (life) and ethos (ethics): it is ethics concerning the problems of life. Now life, particularly human life, is always life in the body and with the body. It is not only in the body and with the body: human life is also something else. But there is no doubt that precisely because human life is always a life in the body and with the body.

A 4.1 kg male neonate with a diagnosis of double-inlet left ventricle with dextro-transposition of the great arteries was intubated shortly after birth due to respiratory insufficiency. The initial management consisted of a successful Stage I hybrid procedure. Persistent respiratory insufficiency led to cross-sectional imaging and bronchoscopy that demonstrated severe airway compression from a dilated main pulmonary artery. A Norwood procedure with Blalock–Thomas–Taussig shunt was performed at 1 month of age to relieve the airway obstruction. The patient was discharged home on room air at 2 months of age. This case highlights a unique single-ventricle anatomic variant with airway compression, which was successfully managed with deferred Norwood palliation.

Anatomical configurations where the viscero-atrial structures do not follow the usual arrangement or mirror-imaged arrangement is described conventionally as heterotaxy. Isomerism in the context of the congenitally malformed heart is a situation where some paired structures on opposite sides of the left–right axis of the body are, in morphologic terms, symmetrical mirror images of each other. It encompasses two separate entities, right and left isomerism, the former being usually associated with asplenia and the latter with polysplenia. We report herein a rare case of left isomerism that is associated with asplenia in a 4-year-old girl.

Published: July 2024

Dual drainage of a pulmonary vein is an unusual anomaly of pulmonary venous drainage. While being evaluated for hypertension, a child was found with dual drainage of the upper left lobe through a vertical vein that connects to the normal pulmonary vein as well as the innominate vein with no symptoms from his effective left-to-right shunt.
Effect of table height on supraglottic airway insertion (I-gel): A randomized control trial
Authors: Kumari Poonam , Kumar Amarjeet , Sinha Chandni , Kumar Ajeet
Published: July 2024

Background and Aims:

Both operating table height and patient level in relation to the anesthesiologist influence supraglottic airway device (SAD) insertion and task performance in terms of physical and mental workload. The aim of the study was to find out the appropriate table height during SAD insertion in terms of time taken for insertion, success rate, ease of insertion, and anesthesiologist comfort.

Material and Methods:

In this randomized controlled trial, 90 American Society of Anesthesiologists physical status I and II patients, aged between 18 and 60 years, scheduled for elective surgery were recruited. Patients were divided into three groups of 30 each. During SAD insertion, the table height was adjusted so that the patient’s forehead was at the level of 5 cm above the xiphoid process in group I, at the level of the xiphoid process in group II, and at the level of 5 cm below the xiphoid process in group III of the anesthesiologist. We measured SAD insertion time, first attempt success rate, ease of insertion, and anesthesiologist comfort during the procedure.

Results:

The SAD insertion time (in seconds) was lower in group III than in groups I and II, and a significant difference was found between the groups (P < 0.05). The mean ease of insertion score, anesthesiologist comfort, and the first-attempt success rate of SAD insertion were higher in group III than in groups I and II, and the difference among the groups was statistically significant (P < 0.05).

Conclusions:

We conclude that the lower table height with the patient’s forehead at the level of 5 cm below the xiphoid process of the anesthesiologist is ergonomically more efficient during SAD (I-gel) insertion. This table height is also more comfortable for the anesthesiologist during SAD placement.
Efficacy of ultrasound-guided suprazygomatic maxillary nerve block on emergence agitation and postoperative analgesia after septorhinoplasty: A prospective randomized trial
Authors: Afandy Mohamed E. , Abd Elghafar Mohamed S. , Shoukr Tarek G. , El Mourad Mona B.
Published: July 2024

Background and Aims:

Emergence agitation (EA) is frequently encountered following nasal surgeries, and postoperative pain is a significant contributing element. We aimed to assess the role of suprazygomatic maxillary nerve (MN) block (SMB) guided by ultrasound (US) in lowering EA incidence and enhancing analgesia quality in septorhinoplasty cases.

Material and Methods:

Sixty cases aged 18–60 years, of both genders, categorized by the American Society of Anesthesiologists (ASA) I–II and listed for septorhinoplasty, were randomized to receive general anesthesia (GA) with either no block (the control group) or combined with bilateral US-guided SMB (the SMB group). The incidence of EA, postoperative pain scores, total rescue 24-hour analgesic consumption, and incidence of adverse events were all noted.

Results:

EA incidence was significantly reduced in the SMB group than in the control group (five patients (16.7%) vs 14 patients (46.6%), respectively; P = 0.026). Pain scores at 30 minutes and 1, 2, 4, and 6 hours postoperative were significantly decreased in the SMB group (P = 0.024, 0.000, 0.000, 0.009, and 0.038, respectively), with significantly less morphine consumption at 24 hours postoperative in the SMB group compared with the control group (P = 0.000). No serious adverse events were noted.

Conclusions:

Preemptive application of US-guided SMB was effective in lowering EA incidence. Furthermore, it enhanced the analgesic quality and reduced the requirement for rescue analgesics in patients undergoing septorhinoplasty.

Authors: Garzali Ibrahim Umar , Sheshe Abdulrahman Abba , Suleiman Ibrahim Eneye , El-Yakub Amina Ibrahim
Published: July 2024

Introduction:

Portal hypertension is characterised by an increase in portal pressure. It may be a result of cirrhosis of the liver or non-cirrhotic hepatic and portal vein diseases. Non-cirrhotic portal hypertension (NCPH) is caused by a heterogeneous group of diseases affecting the liver and extrahepatic locations. In our setting, the most common cause of NCPH is schistosomiasis. We describe our experience in the surgical management of NCPH.

Materials and Methods:

This is a single centre retrospective study of all patients who had surgery for NCPH from January 2015 to December 2023 was retrieved for data collection. Data collected included the cause of portal hypertension, age, gender, indication for surgery, type of surgery, and outcome of surgery. Data were analysed using SPSS version 26.

Results:

A total of 13 patients had surgery for NCPH. The most common cause of NCPH was hepatosplenic schistosomiasis in 10 patients, whereas the remaining 3 patients had idiopathic NCPH. The indication for surgery was upper gastrointestinal bleeding secondary to oesophageal varices refractory to endoscopic therapy. The surgical intervention of choice includes the modified Sugiura procedure in five patients and the Hassab procedure in eight patients. Variceal rebleeding was seen in two patients within 1 year of surgery (15%) and in only three patients within 3 years of surgery (23%).

Conclusion:

Surgical treatment of NCPH is associated with good outcomes in patients with failed endoscopic therapy.
Recovery of Learning and Memory Deficits Despite Persistent Pyknosis of the Hippocampal Pyramidal Neurons of Adult Hydrocephalic Mice
Authors: Ajiboye Ebenezer O. , Olopade Funmilayo Eniola , Femi-Akinlosotu Omowumi Moromoke , Shokunbi Matthew Temitayo
Published: July 2024

Background:

The hippocampal alterations resulting from hydrocephalus are associated with various cognitive dysfunctions. Reduced learning and memory are early functional deficits that recover with time in experimental hydrocephalus. This study investigated the recovery processes of learning and memory loss in relation to the morphology of hippocampal pyramidal neurons and the degree of expansion of the ventricles.

Materials and Methods:

Hydrocephalus was induced in adult mice by intracisternal injection of sterile kaolin while controls received sham operation. Neurobehavioral tests for memory and learning were conducted, after which the animals were sacrificed in batches: 7 (acute) and 28 (subacute) days postinduction. After sacrifice, mice were categorized into mild and moderate hydrocephalus, and their fixed brain samples were processed for hematoxylin, eosin, and Nissl stains.

Results:

In moderate acute hydrocephalus, the indices of learning and memory were reduced escape latency (67.20 ± 12.83 s), number of platform crossing (4.000 ± 1.658), duration in platform quadrant (4.000 ± 1.658), and percent of total investigation (44.857% ± 3.981%) but not in the subacute stage. Pyknotic indices (PI) were significantly higher in the cornu ammonis (CA)1 and 3 regions in all hydrocephalic groups than in controls. However, within groups, PI was significantly higher only in the CA1 of moderate acute (28.149% ± 1.875%) compared to moderate subacute hydrocephalic group (12.903% ± 3.23%).

Conclusion:

Hydrocephalus caused cellular injury to the hippocampus associated with spatial learning and memory deficits. However, these functional deficits were partially reversed in moderate subacute hydrocephalus despite the persistence of the structural alterations in the CA1 and CA3 subregions.

Published: July 2024

Background:

Surgical training is hands-on, with residents requiring optimal exposure to patients for optimal training and adequate experience. Thus, despite the increased usage of virtual, non-physical resources for medical education during the pandemic, orthopaedic surgical training still suffered adversely.

Objectives:

To explore the overall impact of the COVID-19 pandemic on Orthopaedic surgery training, teaching and practice amongst residents in southern Nigeria.

Materials and Methods:

This was a cross-sectional prospective study involving 54 senior orthopaedic surgery residents in southern Nigeria. Data were collected using a semi-structured online-based questionnaire created on the Google Forms and sent via online platforms (e.g., WhatsApp and Telegram). Descriptive and inferential analysis was done using Statistical Package for Social Sciences (SPSS). Consent was also obtained from all respondents.

Results:

A total of 54 orthopaedic surgery residents responded to our questionnaire. About 71.7% of the residents surveyed reported reduced exposure to surgical cases in general, and 70.3% reported reduced operative teaching exposure. About 68.5% of the respondents reported reduced opportunities for surgical skills acquisition training. More than half of respondents (63%) reported no changes in morbidity/mortality of orthopaedic cases witnessed and performed. The majority of the respondents agreed to a slight decrease in the availability of implants and courses (40.7%) whereas 44.4% affirmed an increase in the cost of training. Overall, 70.4% believed that the impact of COVID-19 on orthopaedic surgical training has been slightly negative. The average rating for experience on alternative learning methods – virtual video conferences, pre-recorded lectures, in-person small group meetings and surgical simulation activities was 2.26 on a scale of 1–4 (decreasing order of satisfaction).

Conclusion:

The COVID-19 pandemic caused significant changes in orthopaedic surgery training, with low cases exposure and reduction in operative teaching being the most significant changes and the resultant increase in alternative forms of training and skill acquisition.
