Situation anthropologique fondamentale, tendresse et situation analytique
Authors: Escardó Zaldo Lorenza
Published: July 2024

Le travail en tant que psychothérapeute psychanalytique avec les cas cliniques actuels : pathologies limites, somatisations, les genres non binaires, nous poussent encore vers la recherche. La Théorie de la séduction généralisée de Jean Laplanche s’est révélée particulièrement utile et fructueuse. En dialogue avec cette théorie, l’ouverture métapsychologique et technique proposée par Laurent Tigrane Tovmassian, avec sa proposition de réhabiliter le concept de tendresse, est une source d’inspiration intéressante pour maintenir le débat en psychanalyse.
La tendresse, affect premier associé à la pulsion primitive : Tact-Pulsion
Authors: Prat Régine
Published: July 2024

Prendre en considération le développement du psychisme prénatal met en évidence le rôle premier du tact comme soubassement de la pulsion : Tact-Pulsion génère une mémoire de forme qui constituera le fil rouge de tout le développement ultérieur. La tendresse y est associée comme représentant primitif de l’affect. Cet élargissement de notre modèle métapsychologique a des connaissances théorico-cliniques considérables.
« Objets inanimés, avez-vous donc une âme, Qui s’attache à notre âme et la force d’aimer ? »
Authors: Davoine Françoise
Published: July 2024

La tendresse permet de dépasser le tabou qui met l’humain au sommet de l’échelle des êtres, en reliant les personnes chosifiées par des diagnostics débilitants, et par des instances sans foi ni loi pour qui l’autre n’existe pas, à l’âme des choses, des plantes ou des animaux. Des exemples de ce transfert spécifique sont pris chez des auteurs littéraires, considérés par Freud comme « nos meilleurs alliés ».
La tendresse en idéal. Les enseignements d’une rencontre esthétique avec l’œuvre de Chana Orloff
Authors: Candilis-Huisman Drina
Published: July 2024

L’amour qu’une mère ou un père porte à son enfant participe de cette proximité affective d’une certaine nature qu’on nomme tendresse. Le couplage des deux notions est pourtant loin d’être absolu. L’amour peut se proclamer, la tendresse est presque ineffable, peut-être du fait que, contrairement à l’amour, elle s’inscrit dans un partage. En nous attachant au travail d’une artiste, Chana Orloff (1888-1968), marquée par une vie d’exils et de traumas, nous explorons la façon dont la dimension d’idéal accordée aux sentiments partagés de tendresse entre une mère et son enfant peut contribuer à la sublimation de la destructivité primaire et rencontrée dans la réalité.

Authors: Mestre Louise , Veyret-Morau Maurween
Published: July 2024

L’hôpital Avicenne évalue et suit des mineurs de retour de zone d’opérations de groupements terroristes depuis sept ans. L’équipe a ainsi pu mesurer l’importance de la prise en charge en psychomotricité pour ces enfants, souvent séparés de leur famille et souffrant de trauma complexe ou développemental. À travers une séquence de soins en psychomotricité et psychothérapie avec deux enfants aux trajectoires familiales complexes, l’article met en évidence les bénéfices d’une prise en charge conjointe. Les auteures développent l’incidence de cette configuration sur la clinique, la complémentarité de ces espaces, les enjeux psychosomatiques du trauma, l’impact de ces derniers sur le développement psychomoteur de l’enfant et de l’adolescent, enfin la dynamique à l’œuvre dans le contre-transfert.
Effondrement du sentiment de continuité d’être, filiation narcissique et radicalités
Authors: Angioli Michel
Published: July 2024

À travers le cas clinique d’un jeune homme violent, radicalisé politiquement aux thèses de l’ultra-droite et suivi en psychothérapie à raison de deux fois par semaine pendant près de deux ans, l’article aborde les questions de la radicalisation à travers le prisme de l’effondrement du sentiment de continuité d’être. Ce sentiment s’effondre plus particulièrement au moment de son adolescence du fait d’une histoire traumatique démaillante affectant ses contenants individuels, familiaux et collectifs réactivant ainsi ses angoisses primitives de désunification corporelle. Ce jeune trouvera dans le modèle de la filiation narcissique un « maillage » de substitution pour faire face à ces angoisses primitives.
La parentalité au défi de l’autisme en Algérie
Authors: Boussafsaf Zoubir , Metz Claire
Published: July 2024

L’autisme constitue un trouble spécifique caractérisé par des altérations importantes de la communication et des interactions sociales. La naissance d’un enfant autiste affecte l’ensemble de la famille, notamment les parents, et la parentalité considérée comme le processus interactif entre les parents et l’enfant, assurant le développement de l’enfant et l’accès au devenir parent. L’article fait part d’une recherche clinique réalisée à Constantine au moyen d’entretiens individuels semi-directifs auprès de 18 parents d’enfants autistes faisant l’objet d’une analyse thématique de discours. Cette étude permet de comprendre la parentalité dans le contexte de la famille algérienne prise entre modernité et croyances traditionnelles et de saisir les défis auxquels sont confrontés ces parents en l’absence de structures de prise en charge spécifique et de scolarité des enfants autistes.

Authors: Njifon Nsangou Hassan , Dongmo Nguefack Ingrid Vanilla
Published: July 2024

Le trouble du spectre de l’autisme se manifeste par des difficultés d’interaction, de communication sociale et des comportements répétitifs commençant tôt dans la vie d’un enfant. Ce texte explore, à travers des entretiens, le vécu de quatre pères d’enfants atteints de ce trouble au Cameroun. Les résultats de cette étude montrent la souffrance des pères et leur sentiment d’impuissance, qui engendre chez eux une blessure narcissique tout en renforçant leur sentiment d’étrangeté concernant ce handicap et l’enfant atteint. L’étude montre la nécessité d’un soutien psychologique des pères dans le processus de soin des enfants atteints pour en faire, au même titre que les mères, une ressource pour les professionnels du soin et pour l’enfant atteint.

Published: July 2024

The application of machine learning techniques for monitoring and diagnosing faults in photovoltaic (PV) systems has been shown to enhance the reliability of PV power generation. This research introduced a novel machine learning classifier for fault diagnosis in PV systems, utilizing an ensemble algorithm known as extra trees (ETC). The study initially proposed a system with two PV modules and developed a low-cost Arduino-based data logger to gather data from the PV system in free-fault and faulty conditions. Subsequently, the study evaluated six other advanced classifiers for fault diagnosis in PV systems, namely logistic regression (LR), k-nearest neighbor (kNN), support vector machine (SVM), decision tree (DT), AdaBoost, and random forest (RF) models using the collected data from the proposed PV system. The assessment of the various models' performance indicated that the extra trees model exhibits superior classification capabilities for partial shading (PS), open circuit (OCF), partial shading with bypass diode disconnected (PSBD), and combined partial shading with bypass diode disconnected plus open circuit (PSBDOC) faults. The results demonstrated that the new ETC classifier achieves an accuracy of 92%, surpassing the 91%, 87%, 7%, and 59% accuracy of the RF, DT, kNN, and LR classifiers, respectively. This highlights the effectiveness of the extra trees model in enhancing fault detection and classification by distinguishing between open circuits and twin faults. Consequently, these results can be utilized to develop advanced diagnostic tools for photovoltaic systems, thereby improving the reliability of solar technology and accelerating the rate of installation.

Authors: Chavada Anil , Pathak Nimisha , Khirsariya Sagar R.
Published: July 2024

This article presents and analyzes a mathematical model for smoking-related cancer that involves fractional-order derivative with seven different compartments. The model uses the ABC fractional derivative to describe the transmission dynamics of cancer caused by the smoking habit. We employed the Adams-Bashforth-Moulton method to find the numerical and graphical results of the model and we achieved a good level of accuracy. The existence and uniqueness of the model solution were established using Banach's fixed-point theory. For stability, we investigated the steady state points and basic reproduction number of the system. Additionally, the model's stability was discussed using the Hyers-Ulam criterion. The two-dimensional (2D) and three-dimensional (3D) simulations were performed for the different compartments and for the various values of the fractional-order parameters.
Evaluation of the efficacy of rice bran and sesame oil for producing nutritionally-superior quality functional tofu
Authors: Sengupta S. , Bhowal J.
Published: July 2024

Paneer prepared from edible-quality de-oiled soy flour is known as tofu. Functional tofu was augmented with specific antioxidants such as oryzanol and lignan obtained from rice bran oil (RBO) and sesame oil (SO), respectively. All the fortified and control tofu were evaluated for physicochemical (proximate composition, oxidative stability, antioxidant activity, penetration, and color property), microbiological, and sensory properties. The total viable count and yeast and mold counts increased slowly in the samples stored at 4 °C in the refrigerator for 9 days. Fortified tofu showed higher oxidative stability and antioxidant activity than the control tofu during storage conditions. Additionally, tartaric acid-coagulated tofu retained its quality attributes, especially taste and overall acceptability, during refrigerated storage. Functional tofu aided in an innovative technological technique for making functional non-dairy products with boosted healthy constituents.

The deterioration of anthropological work in Mexico during the 21st century
Authors: Reygadas Luis
Published: July 2024

This article analyzes how the working conditions for Mexican anthropologists have deteriorated throughout the last few decades. Until half a century ago, only a few dozen professional anthropologists practiced in Mexico, and most of them had access to stable, well-paid jobs in academia or government agencies. Today there are over 7000 of them working in a wide range of fields, mostly in temporary jobs with low salaries. Drawing from the data gathered in the Historical Catalogue of Theses on Social Anthropology in Mexico (RedMIFA 2018) and the Survey on Professional Practice and Working Conditions of Anthropologists in Mexico (CIEPA-CEAS 2016), this paper begins by outlining the decline of working conditions for Mexican anthropologists, focusing primarily on the younger generations. An analysis follows of the main factors that have contributed to the current situation, and the article closes with a brief commentary on the effects of precarious working conditions for the production of anthropological knowledge. The implications here are paradoxical: on the one hand, most professionals currently work in fields other than academia, thereby diversifying anthropological practice, and on the other there is a marked tendency towards the academization of professional anthropological education.
MOTOR IMAGERY SIGNAL CLASSIFICATION FOR BRAIN–COMPUTER INTERFACE USING RideNN WITH HOLO-ENTROPY FEATURES
Authors: Wankhade Megha M. , Chorage Suvarna S.
Published: July 2024

The brain–computer interface (BCI) database’s motor assessment depends heavily on the motor imagery (MI) signal classification. By examining the multiple patterns of different creative tasks in the electroencephalogram (EEG) signals, the intention of humans is translated into computer-based commands in the MI-based signals of BCI data. Nevertheless, low accuracy and efficiency are issues with MI–EEG signals’ classification because of the low signal-to-noise ratio, huge individual differences, overall volatility, and complexity in the signal. To overcome these problems, this research proposes a rider optimization algorithm-based neural network (ROA-based NN) to classify the MI signals effectively. Pre-processing is done after collecting the dataset of raw EEG signals. The suitable electrodes, such as C3, C4, and Cz, are subsequently chosen from the MI signals. Using the holo-entropy-based WPD feature extractor, tunable Q-factor wavelet transform (T-QWT), and common spatial patterns in the model, the pertinent features are extracted from the chosen electrodes. The developed holo-entropy-based WPD feature examines the electrode structure’s association. As a result, the most diverse signals are removed from the chosen electrodes before being input into the proposed RideNN classifier, where the proposed ride optimization algorithm optimizes classification performance and correctly predicts and classes the output from the MI signals that have been analyzed. The developed RideNN classifier recognizes the patterns more accurately processes more data and tackles the noise and incomplete data effectively. Utilizing the parameters of accuracy, sensitivity, and specificity, the results are evaluated. The PROA-based RideNN and the combined features obtain the maximum accuracy of 92.24%, sensitivity of 92.26%, and specificity of 92.14% for the BCI competition-IV 2a database. The qPROA-based RideNN and the combined features obtain the maximum accuracy of 92.11%, sensitivity of 91.98%, and specificity of 92.35% for the BCI competition-IV 2b database.
Microstructural Analysis and Microhardness Evaluation of Stainless Steel SS304 Joints Utilizing Microwave Hybrid Heating (MHH) and Cold/Heat Processing: A Fuzzy Logic Approach

Published: July 2024

Stainless steel SS304 is extensively used in dental applications for its high strength, hardness, and corrosion resistance. However, Conventional dental joining techniques such as soldering and fusion welding, reliant on elevated temperatures and toxic fluxes, present substantial oral health risks, leading to potential health deterioration due to toxic emissions. The study proposes the utilization of a microwave hybrid heating process (MHH) for joining stainless steel SS304 (15mm × 7.9mm × 0.2mm) and pure zinc metal powder (44 µm, 99% purity), citing its enhanced efficiency, speed, precision, and diminished environmental footprint as key characteristics without fume. It explores heat processing between 30°C to 60°C and cold temperature processing from 0°C to 10°C to analyze alterations in hardness properties and microstructures. The study identified a direct correlation between temperature and microhardness, observing an increase in microhardness with rising temperatures. Optimal microhardness of 208.6 HV was achieved at 60°C during a 3 min heat treatment. Cold temperatures induced slight deformation and grain transformation, while heat treatment enhanced grain density and hardness, particularly in the strongly bonded boundary layer, with experimental and predicted values using Fuzzy logic showing promising outcomes and errors below 10%. In conclusion, the study demonstrates that achieving a specific hardness value in stainless steel joints is highly desirable for dental applications, alongside the observation of favorable microstructures. These findings underscore the potential of MHH to propel dental technology forward and promote sustainable practices while addressing environmental concerns.

Published: July 2024

Additive manufacturing, specifically Laser Powder Bed Fusion (PBF-LB), has gained prominence for its capability to produce complex near-net-shaped components. While PBF-LB offers advantages such as lightweight construction and cost-effectiveness, post-processing remains crucial to meet specific design requirements. This study investigates the post-processing technique of severe shot peening (SSP) on PBF-LB-manufactured 316L stainless steel, a material widely used for its favorable mechanical properties and corrosion resistance. The research focuses on the enhancement of bending fatigue properties through SSP treatment, examining the influence of material thickness on fatigue behavior. Comparative analysis reveals the effectiveness of SSP in significantly improving fatigue strength irrespective of variations in material thickness. Mechanical properties are explored for different thicknesses subjected to SSP treatment. Electron Backscatter Diffraction (EBSD) is employed to scrutinize the surface properties of the samples, providing knowledge on the microstructural changes induced by SSP. The study contributes to the understanding of the role of material thickness in the context of SSP treatment, offering a comprehensive exploration of the mechanical and fatigue characteristics of PBF-LB-manufactured 316L stainless steel.

Published: July 2024

The current study proposes to investigate the thermal, wettability and mechanical properties of a low temperature SnBi solder. The main aim is to investigate the performance of the SnBi solder alloy with different Bi composition. The study also establishes the relationship between melting temperature, spreading area and tensile stress of the SnBi with different Bi composition at different low reflow temperatures. The thermal and wettability tests are conducted experimentally, while the mechanical test will be analysed via finite element analyses (FEA). The single shear lap test method was adopted for the simulation. The thermal properties of the SnBi solder are investigated using the differential scanning calorimeter (DSC). The reflow temperature selected ranges from 160 °C to 220 °C to accommodate the purpose of low temperature soldering. Wetting test results showed that spreading area of Sn48Bi solder alloy increased to 28.1 and 42.88 at 180 °C and 210 °C respectively. The increase in the Bi composition reduced the tensile strength regardless of the increase of the reflow temperature. The preliminary results commend the characteristics of the SnBi solder as a possible alternative to the Pb solder.

Conceptual Design and Proof-of-Concept Demonstration of Electric Unmanned Aerial Vehicle for Logistics at High Altitude
Authors:   Indian Institute of Technology Kanpur, Raj N. ,   EndureAir Systems, Padmakumar R. , Jain V. , Abhishek Mr.
Published: July 2024

This paper explores the conceptual design and proof-of-concept demonstration of an unmanned rotary wing Unmanned Aerial Vehicle (UAV) for logistics at high altitude areas. An iterative design methodology is developed using sizing formulas to carry out trade-off study for conceptual design of an unmanned helicopter based on the specified mission requirements. The key mission scenario involves taking off with 25 kg payload at an altitude of 5500 meters above mean sea level (AMSL), climbing 500 m above ground level (AGL), cruising to the delivery target, dropping of the payload while hovering, returning, and descending 500 meters for final landing. Two distinct mission profiles are explored for design: one with a total hover endurance of 40 minutes and the other with complete mission comprising of takeoff, climb, cruise, descent and landing. The methodology employed evaluates key design factors, including component weight allocation using empirical approaches. Hover Out of Ground Effect (HOGE) power is determined using Blade Element Momentum Theory (BEMT) and uniform inflow based aerodynamic model is used for climbing, descending, and forward flight power calculations. A blade optimization study is also carried and selection of high lift airfoil, reduction of number of blades and use of −15° linear twist, results in 14% reduction in hover power. The final design choice is driven by trading-off between tip speed and control bandwidth availability. The design is experimentally validated by fabricating an approximately half-scaled prototype which is flight tested at 5000 m altitude. This paper demonstrates the feasibility of an electric powered tandem rotor UAV for high-altitude payload missions, offering a framework for precise design in this challenging environment.

Authors:   Auburn University, Strickland Stephen ,   R1202 LLC, Virasak Jacques , Hartfield Roy , Ahuja Vivek
Published: July 2024

The effectiveness of the counter-torque capabilities of rotorcraft tail rotors has undergone extensive study and development due to its critical role in balance and maneuverability. The Fenestron provides an interesting alternative to the conventional open tail rotor, improving upon several key elements, but still demonstrates drawbacks in others. This paper seeks to provide a side-by-side comparison of Fenestron and open tail rotor performance, in terms of thrust and power, using the mid-fidelity surface-vorticity panel-method flow solver FlightStream® to simulate Fenestron and open rotor configurations in hover and cruise conditions. While this work is not a comprehensive analysis, as it does not compare to experimental data, nor implements exact geometrical representation, it does propose trends between the Fenestron and open tail rotor cases.
Design and Testing of a Highly Redundant Electro-Mechanical Actuator for Aircraft Primary Flight Control Applications
Authors:   Airbus Helicopters Technik GmbH, Arnold Uwe , Haar Jan
Published: July 2024

In order to answer the demand for an electrical primary flight control system for smaller manned or unmanned VTOL aircraft, a novel rotatory actuator and the related control periphery has been designed, manufactured and tested. In contrast to most systems used for these applications today, the presented approach uses an architecture that from the beginning considers the option for certification to civil manned rotorcraft standards. The key idea was to design a single unit comprising all necessary redundancy and failure handling features that simplex COTS components are typically lacking. The over-all architecture, therefore, follows a dual-duplex concept with a minimum of single-pointfailure elements. This paper sketches the layout of the mechanical, electrical, and control unit components, explains the relevant design choices, and presents the realization of a demonstrator system. The subsequent sections describe the successful validation through a series of static and dynamic tests. Finally, the installation of a complete set of actuators onto the reference target platform, an ultra-light coaxial rotor helicopter is presented. Fitting such system to this beforehand manually/mechanically controlled aircraft now enables its unmanned operation. Other foreseen applications are briefly mentioned as well.

Authors: Li Wenyan , Liu Xin , Wen Yinghua , Wu Junying , Giordani Federico , Stecco Carla
Published: July 2024

Lower limb spasticity and clonus are common sequelae after cerebral stroke. An important part of their etiopathogenesis has been related to the peripheral component of spasticity. Rheological properties of the tissues seem to be involved. Several studies highlighted anatomical and functional changes in the connective structures. The fasciae might be implicated in the pathological process. Thus, this study intends to investigate the effect of the Fascial Manipulation (FM) technique on triceps surae in stroke patients through a clinical randomized controlled trial, to provide a reference for clinical treatment of lower limb spasticity and ankle clonus. A total of 40 patients with post-stroke ankle clonus were selected and divided into a control group and an observation group by random number table method, with 20 cases in each group. Both groups received conventional rehabilitation therapy, while the FM group received Fascial Manipulation based on conventional rehabilitation therapy. Before the first treatment and after 3 weeks of treatment, the Comprehensive Spasticity Scale (CSS), the Passive Range Of Motion (PROM), the simplified Fugl-Meyer motor function score (FMA), and the Modified Ashworth Scale (MAS) were used to assess the degree of ankle clonus, ankle passive range of motion, and lower limb motor function of the two groups of patients. Before treatment, there was no statistically significant difference between the control group and the FM group in terms of CSS, PROM, FMA, and MAS of the affected lower limbs (P>0.05). After 3 weeks of treatment, the CSS and MAS of the affected lower limbs in the control group and FM group decreased, while PROM and FMA increased compared to pre-treatment evaluation, with statistically significant differences (P<0.05). Moreover, the FM group showed a statistically significant decrease in CSS and MAS, as well as an increase in PROM and FMA, compared to the control group (P<0.05). Conclusions: Fascial manipulation in addition to conventional therapy can effectively reduce spasticity and ankle clonus in stroke patients in a short time, and improve the passive range of motion of the ankle joint and the function of lower limbs.

Published: July 2024

The sustainability of breastfeeding remains a challenge for primiparous mothers. Empowering women through home visits by midwives needs to be enhanced to ensure the continuity of breastfeeding. This research aimed to compare the effectiveness of the SETIA (Self-Empowering Women, Empathy, Trust, Intimacy, and Affection) program with a standard program in assisting primiparous mothers to breastfeed their babies after one month. A total of 50 primiparous participants were divided into two groups through simple random sampling. The standard group received four home visits, while the SETIA group received five home visits within one month postpartum. The breastfeeding competency variable was evaluated after one month using the World Health Organization (WHO) instruments and interviews about exclusive breastfeeding. The variables were analyzed using comparative statistics. The results showed no significant difference between the standard and SETIA groups, with Mann-Whitney U values of 253.5 and Wilcoxon values of 578.5 (p-value=0.086, α<0.05). However, there is evidence that the intervention group managed breastfeeding problems better, and more mothers continued breastfeeding after one month. Therefore, the authors suggest more frequent home visits to help new mothers adapt to their breastfeeding roles, especially in the first week after birth. Further research is needed to assess exclusive breastfeeding after six months in both groups.

Published: July 2024

Background

End-stage renal disease (ESRD) patients on maintenance hemodialysis (MHD) are highly vulnerable to severe manifestations of coronavirus disease 2019 (COVID-19) as increased risk of thromboembolic disease and worsened neuropsychiatric status.

Aim

To assess the long-term thrombotic and neuropsychiatric sequelae of severe acute respiratory syndrome corona virus 2 in post-COVID-19 ESRD patients on MHD.

Patients and methods

We followed for 12 months, 35 clinically stable HD patients on MHD who were confirmed or highly suspected for COVID-19 by positive severe acute respiratory syndrome corona virus 2 RT-PCR and/or high probability on high-resolution computed tomography chest imaging. We recorded demographics, HD and COVID-19 related data, thromboembolic history, and psychiatric history. We recorded baseline and follow-up complete blood count with differential counts, D-dimer, prothrombin time, international normalized ratio, and high-resolution computed tomography chest findings. We assessed post-COVID-19 neuropsychiatric sequelae using the Arabic versions of Hamilton’s depression rating scale and Taylor’s manifest anxiety scale.

Results

Total leukocytic count, lymphocytes, and platelets were significantly lower during infection than preinfection, 6 months, and 1-year postinfection (P<0.001, P=0.003, P=0.014, respectively). Six months after infection, d-dimer levels were higher than normal values. The incidence of vascular access thrombosis was 25.7%. The scores of Hamilton’s depression rating scale and Taylor’s manifest anxiety scale were high [25 (interquartile range; 17–28) and 26 (interquartile range; 19–33)], respectively, and the prevalence of depression and anxiety symptoms were 94.3 and 85.7%, respectively.

Conclusions

During infection, ESRD patients showed significantly lower total leukocytic count, lymphocytes, and platelets than preinfection, 6 months, and 1-year postinfection. They had high levels of d-dimer 6 months postinfection and a high risk for vascular access thrombosis. Their psychological wellbeing was markedly impaired by the pandemic resulting in depression and anxiety.

Published: July 2024

This study offers a comprehensive analysis of risk factors and clinical impact of cytomegalovirus (CMV) reactivation between patients undergoing fully matched sibling or haploidentical hematopoietic stem cell transplants in the context of acute leukemia. CMV viremia showed a significant difference, especially when comparing post-transplant cyclophosphamide (PTCY) recipients between the two groups, with a higher incidence in the haploidentical arm. Furthermore, among those experiencing post-transplant CMV reactivation, a statistically significant higher incidence of acute graft-versus- host disease (GvHD) was observed. However, no statistical significance was found correlating CMV reactivation with relapse. These insights highlight the nuanced differences and similarities between the two transplant types, emphasizing the need for tailored clinical strategies based on the unique challenges posed by each transplant type.

This randomized controlled clinical trial was conducted in Isfahan, Iran, from April 2017 to June 2021 and included 120 patients with syncope. Eligible children and adolescents (aged 6–18 years) who met inclusion criteria were recruited by the simple sampling method and then assigned randomly into two groups. The intervention group (n = 60) received routine self-care recommendations such as dietary advice, behaviors to prevent syncope, and counter-pressure maneuvers along with tilt training, while the control group (n = 60) received self-care recommendations without tilt training. The education training included two face-to-face sessions, each of which lasted for 45–60 min. Then, both groups were followed up by telephone (once a month) for six months. A researcher-made self-care questionnaire and Pediatric Quality of Life Inventory (PedsQL™ 4.0) were completed for both groups before and after the intervention. Data were analyzed using descriptive and inferential statistical methods.

Results:

The Wilcoxon test results showed a significant difference in the mean scores of physical functioning, emotional functioning, social functioning, school functioning, psychosocial functioning, understanding of health, and total QoL in the intervention and control groups before and after the intervention (p < 0.05). Also, the paired t-test results showed a significant difference in the mean scores of self-care domains and total self-care in the intervention and control groups before and after the intervention (p < 0.05).

Conclusions:

Self-care recommendations with and without tilt training can improve QoL in children and adolescents with syncope.

Published: July 2024

Background:

As an epidemic, COVID-19 has brought a new shock to the world’s healthcare system. The crisis caused by this disease and the prolonged involvement of communities and healthcare systems have intensified the duties and psychological burden of nurses. The current study aimed to explain the experience of ICU nurses during the COVID-19 crisis.

Materials and Methods:

The present study was conducted using conventional content analysis in 2021. Twenty nurses of the COVID-19 ICU of Ahvaz hospitals were selected by purposive sampling. The main method of data collection was semistructured interview. The process of data analysis was done based on Granheim and Lundman’s approach using MAXQDA-2020. For the scientific rigor of the findings, Guba and Lincoln’s four criteria were abided by. The COREQ (Consolidated Criteria for Reporting Qualitative Research) checklist was used to ensure the study met the recommended standards of qualitative data reporting.

Results:

After data analysis, 22 subcategories, eight categories, and one theme (growth under pressure) were extracted. The eight main categories included (psychological crisis, physical exhaustion, family conflicts, complex care, professional development, expertise, life enrichment, and full support).

Conclusions:

Despite the pressures that ICU nurses faced during the COVID-19 pandemic, they were able to grow by benefiting from positive experiences. These findings can lead to the development and implementation of effective interventions to improve adaptation strategies of nurses, especially those working in the intensive care unit, during the COVID-19 and other future crises.

Published: July 2024

Background:

Resilience is a psychological trait and a protective factor that plays a vital role in coping with Chronic Pain (CP). Despite its importance, research has yet to fully clarify the concept and components of resilience in patients with CP. Accordingly, the present study aims to explain the components of resilience in patients with CP.

Materials and Methods:

The current qualitative study used a conventional content analysis methodology. The research population included all patients with CP who were referred to clinics affiliated with Shiraz University of Medical Sciences (south of Iran) from August 2021 to August 2022. Participants were selected using the purposive sampling method. In-depth semi-structured interviews were conducted with 20 participants to collect information. Data analysis was conducted using MAXQDA 2020 software in conjunction with data collection efforts.

Results:

Generally, in the current study, 30 sub-sub-categories, 11 sub-categories, and five main categories were extracted as components of resilience in patients with CP. The main categories of resilience against CP included the following: 1. emotional self-regulation, 2. psychological flexibility, 3. self-care, 4. appeal to religion–spirituality, and 5. internal resources and individual competencies.

Conclusions:

The present study highlights the different physical, mental, and religious-spiritual strategies that may contribute to resilience against pain. The resilience components identified in this study provide a foundation for healthcare professionals, particularly nurses, to design and implement diverse pain management strategies that enhance adjustment to CP conditions.

Introduction:

Artificial intelligence (AI) is becoming an important part of our lives owing to increased data availability and improved power of computing. One of the recently launched modalities of AI, ChatGPT, is being enormously used worldwide for different types of tasks. In medical context, its use is being explored for clinical queries, academia, research help, etc. Further, literature suggests that parents seek information about health of their children using different Internet resources and would surely turn toward ChatGPT for the same, as this chatbot model is easy to use, generates “one” response, and is available without any subscription. ChatGPT generates a response using text cues and applying different algorithms on prepublished literature but is still in its naïve state; hence, it is imperative to validate the generated responses. Accordingly, we planned this study to determine the clarity, correctness, and completeness of some Frequently asked questions (FAQs) about child’s oral health, from a mother’s perspective.

Methods:

The study design was a vignette-based survey and included a set of 23 questions, for which ChatGPT was interviewed from the perspective of an imaginary parent. The answers responded by ChatGPT were copied “verbatim,” and a Google survey form was designed. The survey form was validated and then sent to 15 pediatric dentists, and the responses were mainly collected on the Likert’s scale with a provision of one open-ended question aiming to determine “what they would have added” to this generated response as an expert in the field.

Results:

The responses on Likert’s scale were condensed and values ≥4 were considered ‘adequate and acceptable’ while scores ≤3, were considered ‘inadequate’. The generated responses and comments mentioned by different respondents in the open-ended question were critiqued in reference to the existing literature.

Conclusion:

Overall, the responses were found to be complete and logical and in clear language, with only some inadequacies being reported in few of the answers.

Introduction:

Intraperitoneal instillation of local anaesthetic agents alone or in combination with opioids, α2 agonists such as Dexmedetomidine have been found to reduce postoperative pain following laparoscopic cholecystectomy. The study was designed to compare the better drug among Bupivacaine alone and Bupivacaine with Dexmedetomidine with respect to their analgesic efficacy and safety profile. in patients undergoing laparoscopic cholecystectomy.

Patients and Methods:

The study was carried out on sixty patients of the American Society of Anaesthesiologists (ASA) physical status I-II of either sex with ages ranging from 18 to 60 years posted for elective laparoscopic cholecystectomy under General Anaesthesia, equally divided into two groups, randomly allocated to one of the Groups using the table of randomization. Group B received Intraperitoneal Bupivacaine 40 ml 0.25% +5 ml normal saline and Group BD received Intraperitoneal Bupivacaine 40 ml 0.25% + Dexmedetomidine1 μg/kg diluted in 5 ml Normal saline.

Results:

The mean heart rate and blood pressure (systolic, diastolic and mean) readings were significantly lower in Group BD than in Group B. The mean duration of analgesia in our study was longer in Group BD (7.5 ± 0.73 hours) when compared to Group B (5.9 ± 0.55 hours) with p-value & 0.0001 and CI 1.27 to 1.9, which was statistically significant. However, the post-operative analgesic requirement (rescue/demand) in Group B was clinically earlier and statistically significant as compared to Group BD. Postoperative VAS score ≥3 was considered the benchmark for providing rescue analgesia in the form of injection of Diclofenac 75 mg IV. In our study, we observed the pain scores via VAS/NRS at 30 min, 1 h, 2 h, 4 h, 6 h, 8 h, 10 h, 12 h, 14 h, 16 h, 18 h, 20 h, 22 h and 24 h postoperatively. A comparison of pain scores from 30 min to 10hrs postoperatively showed a significant difference in both Groups with Group B having significantly higher VAS scores and lower VAS scores with Group BD.

Conclusions:

Our study suggests that there is a shorter duration of action of 0.25% Bupivacaine alone as compared to 0.25% Bupivacaine + Dexmedetomidine. Since the laparoscope is still inside the abdominal cavity the drugs are easy to administer with no adverse effects and with a good safety profile because of the visualization of drug deposition in the right place. Intraperitoneal instillation of Bupivacaine with Dexmedetomidine for postoperative analgesia was very promising as a part of multimodal analgesia in laparoscopic cholecystectomy.
Risk factors of focal maculopathy in patients with type 2 diabetes mellitus with hard exudates: A hospital-based case–control study
Authors: Patra Rajkumar , Bhat Vinayak Ganesh , Goru Krishna Babu , Rao N. Lakshmana
Published: July 2024

Background:

Dyslipidemia and hard exudates of the retina have an intricate association. Increased lipid levels cause increased hard exudates. Many studies found dyslipidemia as an independent risk factor for the development of hard exudates in maculopathy.

Objectives:

The objective of this study was the association between dyslipidemia and the presence of hard exudates among focal maculopathy patients with and without hard exudates.

Materials and Methods:

This was a hospital-based case–control study. This study included 60 patients with focal maculopathy in type 2 diabetes mellitus (DM) with hard exudates. Sixty patients with Focal maculopathy in type 2 DM without hard exudates were taken as control.

Results:

Dyslipidemia was significantly seen (P < 0.05) in cases compared to participants. Total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), and very LDL-C were significantly higher in cases compared to controls. High-density lipoprotein cholesterol (HDL-C) had the opposite outcome. HDL-C was significantly lower in cases compared to controls.

Conclusion:

Dyslipidemia was a strong risk factor for the formation of hard exudates in the macula. An increase in lipid levels increased the hard exudates concentration in the macula and retina.
