LA PRECARIZACIÓN DEL TRABAJO DOCENTE EN EL RÉGIMEN DE ACUMULACIÓN FLEXIBLE
Authors: Zeneida Kuenzer Acacia
Published: October 2022

El artículo tiene como objetivo analizar el proceso de precarización del trabajo docente en el régimen de acumulación flexible, que forma parte del movimiento de precarización del trabajo en general. Para ello, la autora analizó, a partir de su trayectoria de investigaciones de campo en las últimas dos décadas, la precarización del trabajo docente en la transición del régimen rígido hacia el flexible, tomando las relaciones entre trabajo y educación desde el punto de vista ontológico y epistemológico, al describir las bases materiales y superestructurales que la definen. Con base en el caso brasileño, expone cómo la precarización del trabajo docente ocurre a través de la flexibilización de la formación y del trabajo. Concluye que se constituye una cadena de precarización del trabajo docente que corresponde a la cadena de precarización del trabajo en general: para formar trabajadores para el trabajo precario no se necesitan docentes calificados.

Published: October 2022

Review question / Objective: A few studies have addressed the efficacy of hyperbaric oxygen therapy in patients with fibromyalgia. However, these studies have been inconclusive so far. There is no graded evidence in the form of a systematic review or meta-analysis concerning the administration of hyperbaric oxygen therapy to patients with fibromyalgia. The proposed study would be carried out to assess the efficacy and safety of hyperbaric oxygen therapy in reducing pain in patients with fibromyalgia. Primary Objective: To compare the efficacy of HBOT with the standard conventional therapy in patients with fibromyalgia of age 18 years and more. Secondary Objectives: i. To compare the adverse effects (for safety) of HBOT with the standard conventional therapy in patients with fibromyalgia of age 18 years and more; ii. To compare the change in the quality of life, sleep quality, functional impairment, depression, anxiety, and psychological distress by HBOT as compared with the standard conventional therapy in patients with fibromyalgia of age 18 years and more.

Published: October 2022

The mixture design was used to optimize the potential of hydrogenionic and the spreadability of topical hair gel from cocoa shell extract. The influence of the primary hair gel components thickener (0.25 – 0.75%), moisturizer (1-3%), styling polymer (1-3%), humectant (2-5%), adjusting PH agent (0.2-0.4%) and solvent (90.55-95.75%) were studied on two responses of the topical hair gel. The data obtained were fitted to the model with coefficient determination (R2= 0.994 for the pH and 0.9937 for the spreadability) and the lack of fit test shown not significant with a p-value bigger than 0.05. The optimized formulation with each significant factor was established at thickener (0.3%), moisturizer (0.25%), styling polymer (1.5%), humectant (2.99%), adjusting pH agent (0.4%), and solvent (94.57%) with the potential of hydrogenionic value and spreadability at 6.42 and 1.57 respectively. The predicted validation test shows that both values were comparable. This condition showed that the model development could be used to predict future observations within the design range.

The integration of Phase Change Material (PCM) with the Solar Photovoltaic Thermal (PVT) serves as heat storage to enhance the system's performance. Temperature rises have an undesirable effect on efficiency results in a diminishment in the amount of energy produced by the solar panel. Parametric analysis and temperature investigation are involved in improving the performance of the system. The variation of performance will assist in developing an optimized PVT-PCM system. The model is validated by comparison from published journals on the studies related to phase change material implemented in solar PVT. For the variation of mass flow rate, the overall efficiencies achieved by 10 kg/h, 30 kg/h, 50 kg/h and 70 kg/h are 90.82%, 90.54%, 90.48% and 90.46%, respectively. In addition, solar irradiance of 200 W/m2, 450 W/m2 and 800 W/m2 produced 91.17%, 90.82% and 90.33% of overall efficiencies. Increased in flow rate requires stronger pumps which increase the total cost of the system. Therefore, identifying the optimal flow rate might help to achieve an appropriate thermal efficiency while sustaining in low costs. Finally, this paper presented a numerical investigation of PCM acts as promising elements incorporated in the PVT system that has the capability to reduce the temperature of the PVT-PCM system.

L’accueil des huguenots dans les pays du Refuge à la fin du XVIIe siècle
Authors: Krumenacker Yves
Published: October 2022

Les pays du Refuge accueillent les huguenots pour des raisons religieuses, mais aussi économiques. Ils ciblent des métiers précis en accordant des privilèges : exemptions fiscales, dons de terres, liberté par rapport aux corporations, etc. S’ajoutent très souvent le droit de bourgeoisie, la liberté de culte et le traitement des pasteurs. Il y a cependant un durcissement par la suite à cause du trop grand nombre de réfugiés. Les réfugiés choisissent leur destination en fonction des liens antérieurs, familiaux, intellectuels, commerciaux, qu’ils avaient avec certains pays ou grâce aux nouvelles qui leur parviennent par des journaux, des lettres, des affiches, ou par des contacts directs avec des émissaires des différents gouvernements. Mais leur intégration et leur assimilation varient en fonction des conditions d’accueil.
Les épreuves de l’hospitalité : deux voyageurs indiens en France pendant la Terreur (1793-1794)
Authors: Markovits Rahul
Published: October 2022

Au printemps 1793, deux voyageurs indiens, Navazish Khan et Ahmad Khan, débarquèrent à Marseille. Ils étaient en route pour Londres afin de porter plainte de la spoliation dont leur famille avait été victime en 1772 lorsque la ville de Bharuch avait été conquise par l’East India Company. En suivant à la trace les voyageurs au cours de leur passage en France, cette contribution l’envisage comme un cas limite de l’administration de l’étranger pendant la période révolutionnaire. Leurs interactions avec les autorités sont conçues comme autant d’« épreuves » au terme desquelles ils devaient parvenir à établir et faire reconnaître leur identité. Elle met l’accent sur le rôle des intermédiaires qui leur permirent de passer ces épreuves et sur le regard porté par Ahmad Khan sur la nature bureaucratique et comptable de l’hospitalité française.
Alla ricerca di un asilo: gli emigrati francesi a Venezia durante la Rivoluzione
Authors: Dal Cin Valentina
Published: October 2022

Privati del diritto ad un asilo, in qualità di sostenitori della monarchia e nemici della rivoluzione, gli emigrati francesi vissero una singolare condizione di «stranieri politici». Oltre a non poter rientrare in patria per timore di una condanna a morte, furono costretti a spostarsi da uno Stato all’altro, spinti dall’avanzata degli eserciti repubblicani e dalle minacce dei diplomatici francesi. Questi ultimi cercarono di ottenere il loro allontanamento dai luoghi in cui avevano trovato rifugio, come la neutrale Repubblica di Venezia. L’interazione dei suoi organi con i rappresentanti della Repubblica francese permette dunque di approfondire le peculiarità e le contraddizioni dello status di emigrato. Allo stesso tempo, le informazioni raccolte dalle autorità veneziane consentono un’analisi complessiva dei francesi arrivati in laguna negli anni Novanta del Settecento.
Reconnaître, classer et contrôler les Français réfugiés à Venise à la fin du XVIIIe siècle (1790-1797)
Authors: Bertrand Gilles
Published: October 2022

L’usage de noter les arrivées et départs d’étrangers à Venise dans les hôtels se renouvela sous la Révolution du fait de l’afflux des émigrés français. Les Inquisiteurs d’État et les Esecutori contro la bestemmia, entre autres, se mirent de 1790 à 1797 à faire le tri entre exilés, passants et résidents des diverses nations tout en veillant à ne pas s’aliéner le gouvernement français. Si les Français furent une cible privilégiée, le contrôle s’élargit à partir de 1794 aux réfugiés de contrées voisines, Suisses, Piémontais et Génois, et la remontée des informations se précisa depuis les villes de la Terre ferme. Malgré ses limites et contradictions, cette politique déboucha sur une volonté de quadrillage spatial où le souci de localiser les présences de Français réfugiés amena à repenser les stratégies de surveillance de l’ensemble des étrangers, jusque-là dispensés d’exhiber un passeport à Venise en raison de la tradition d’accueil que professait la République.
Transcender les frontières. Surveillance, contrôle, et administration des anarchistes italiens en exil (fin XIXe – début XXe siècle)
Authors: Beugniet Thomas
Published: October 2022

Dans le dernier tiers du XIXe siècle, le mouvement anarchiste italien s’internationalise en raison d’une émigration économique et de la répression intransigeante de l’État italien. Face à la menace anarchiste, celui-ci développe des moyens de surveillance nationaux et transnationaux innovants. L’État italien choisit au tournant des années 1870 de créer une police internationale. Cette présence de l’État italien à l’étranger se manifeste par des procédures de surveillance politique et policière, mais aussi par des pratiques sociales, administratives et judiciaires. Dans cette communication, il s’agit d’étudier la présence de la police italienne en territoire étranger et les moyens utilisés par les autorités italiennes de l’époque pour surveiller, contrôler et réprimer l’activisme et la mobilité des anarchistes italiens en dehors des frontières nationales.

Authors: Khan Ahsan R. , Rosenthal Courtney D. , Ternes Kelly , Sing Ronald F. , Sachdev Gaurav
Published: October 2022

Background

The amount of time spent on the electronic health record is often cited as a contributing factor to burnout and work-related stress in nurses. Increased electronic health record use also reduces the time nurses have for direct contact with patients and families. There has been minimal investigation into the amount of time intensive care unit nurses spend on the electronic health record.

Objective

To quantify the amount of time spent by intensive care unit nurses on the electronic health record.

Methods

In this observational study, active electronic health record use time was analyzed for 317 intensive care unit nurses in a single institution from January 2019 through July 2020. Monthly data on electronic health record use by nurses in the medical, neurosurgical, and surgical-trauma intensive care units were evaluated.

Results

Full-time intensive care unit nurses spent 28.9 hours per month on the electronic health record, about 17.5% of their clinical shift, for a total of 346.3 hours per year. Part-time nurses and those working as needed spent 20.5 hours per month (17.6%) and 7.4 hours per month (14.2%) on the electronic health record, respectively. Neurosurgical and medical intensive care unit nurses spent 25.0 hours and 19.9 hours per month, respectively. Nurses averaged 23 clicks per minute during use. Most time was spent on the task of documentation at 12.3 hours per month, which was followed by medical record review at 2.6 hours per month.

Conclusion

Intensive care unit nurses spend at least 17% of their shift on the electronic health record, primarily on documentation. Future interventions are necessary to reduce time spent on the electronic health record and to improve nurse and patient satisfaction.
Comparison of commercial assays and two-step approach to detect Clostridioides difficile in South Africa
Authors: Singh Sarishna , Newton-Foot Mae , Nel Pieter , Pienaar Colette
Published: October 2022

Background: Clostridioides difficile is the number one cause of hospital-acquired diarrhoea. Accurate diagnosis of C. difficile is of utmost importance as it guides patient management and infection control practices. Studies evaluating the performance of commercially available nucleic acid amplification tests (NAATs) versus algorithms are lacking in resource-limited settings.Objective: This study assessed the performance of three commercially available tests and a two-step approach for the diagnosis of C. difficile infection using toxigenic culture (TC) as the gold standard.Methods: Two hundred and twenty-three non-duplicate loose stool samples were submitted to the National Health Laboratory Service Microbiology Laboratory at Tygerberg Hospital, Cape Town, South Africa, from October 2017 to October 2018. The samples were tested in parallel using the C. DIFF QUIK CHEK COMPLETE enzyme immunoassay (EIA) and two NAATs (Xpert C. difficile and BD MAX Cdiff), and the results were compared to TC. The performance of a two-step approach consisting of the C. DIFF QUIK CHEK COMPLETE followed by the Xpert C. difficile was also determined.Results: Of 223 faecal specimens tested, 37 (16.6%) were TC-positive. The sensitivity and specificity of the C. DIFF QUIK CHEK COMPLETE were 54.1% and 98.9%; Xpert C. difficile, 86.4% and 96.8%; BD MAX Cdiff, 89.2% and 96.8%; and two-step approach, 89.2% and 96.2%.Conclusion: The C. DIFF QUIK CHEK COMPLETE, in a two-step approach with the Xpert C. difficile, performed similarly to the NAATs on their own and offer advantages in terms of cost and workflow in low-resource settings.
Audit of amylase and lipase requests in suspected acute pancreatitis and cost implications, South Africa
Authors: Cook Annie E. , Jalavu Thumeka P. , Zemlin Annalise E.
Published: October 2022

Background: The internationally accepted criteria for the diagnosis of acute pancreatitis (AP) requires two of the three following features to be present: characteristic abdominal pain, elevated serum amylase and/or lipase enzymes, or consistent imaging results. However, sensitivity and specificity can vary depending on the population and cut-off values used.Objective: This study evaluated the suitability of amylase and lipase as first-line diagnostic biomarkers of suspected AP for the local population served by Tygerberg Hospital, South Africa.Methods: This retrospective analysis was conducted in June 2019 using all amylase and/or lipase request data from December 2018. Patient clinical data were included in sensitivity and specificity analyses of amylase, lipase or dual requests for diagnosis of AP. Cost per test data were obtained from the National Health Laboratory Service and used to calculate the total cost of the tests and potential savings.Results: Sensitivity for lipase was 90.0% compared to 50.0% for amylase. Specificity was similar for singular measurements of lipase and amylase. Dual measurement of amylase and lipase showed no improvement in sensitivity (83.3%) and only a minor increase in specificity (97.4%) compared with measurement of lipase alone. The estimated savings was R2522.85 ($174.98 USD), with a potential annual cost saving of R84 423.74 ($5855.69 USD).Conclusion: Lipase was shown to be a more sensitive biomarker compared to amylase for the screening of AP, providing evidence for laboratories to educate local staff and promote improved requesting practices by clinicians. Additionally, preventing unnecessary dual requests may reduce costs.

Authors: Ngwenya Kenneth , Naude Micheline J. , Wissink Henry F.
Published: October 2022

Background: There has been a growing emphasis on airport development strategies as these strategies contribute towards economic growth and development. An aerotropolis as one of the initiatives is a strategy that facilitates the realignment of airports into economic hubs by increasing their scope of activities.Aim: To describe the Durban Aerotropolis strategy and contextualise its socio-economic impacts to the city and region of Durban, KwaZulu-Natal. The socio-economic factors utilised are limited to the environment, people (community) and the economy.Methods: A qualitative research approach was adopted and used sequentially, concurrently and iteratively. The findings and recommendations are based on 12 in-depth interviews and five focus group sessions with participants from the target population.Results: The Durban Aerotropolis development is in its initial stages of adoption, and there is evidence of early positive socio-economic impacts including employment creation, growth in imports and exports and the creation of a competitive environment.Conclusion: The success of the strategy has been attributed to the adoption of novel strategies and concepts that enable improved logistics and mobility planning, connectivity and responsiveness, amongst other critical success factors. This has seen several strategies being considered, including roadway expansions, network designs, mobility platforms and many other infrastructural developments. This will enable purposeful planning to ensure that the region and South Africa are economically viable and competitive.
What is public health ethics for the geriatric community?
Authors: Lategan Laetus , Van Zyl Gert , Kruger Willem
Published: October 2022

Background: A growing ageing community puts additional demands on the public health system. This will contribute to ethical consequences for the health care sector. A public health ethics framework can contribute towards addressing the ethical challenges faced by the geriatric community.Aim: This article intends to contribute to a public health ethics framework for the geriatric community from a South African perspective.Setting: Twenty-two participants from six geriatric institutions, two each in the three provinces, participated in the research. The provinces are the Free State, Northern Cape and North West.Methods: Fifteen statements were rated using a five-point Likert scale questionnaire. The statements were grouped into three indexes, namely what is ethics, what is public health ethics and what is public health ethics for the geriatric community?Results: Ethical behaviour is observable not only from person to person but also through systems, processes and practices. The need is to understand how to apply ethical principles to the working environment. A public health ethic can be understood from applied, professional and social ethics.Conclusion: Public health ethics is the application of health care principles through a professional ethic resulting in care and relationship-building. The core of what public health is should be the basis to identify a public health ethic where the focus is on the community and improvement of the quality of health and well-being of the community.Contribution: No evidence of a public health ethics framework for the geriatric community could be identified in South Africa.
Barriers and facilitators to medicine collection through the CCMDD programme at a Durban Hospital
Authors: Hlongwana Simangele I. , Gray Andrew L.
Published: October 2022

Background: South Africa has rekindled health reform efforts through the implementation of the Centralised Chronic Medicine Dispensing and Distribution (CCMDD) programme, as a precursor towards achieving envisioned National Health Insurance (NHI). The CCMDD programme enables stable patients to collect chronic medicines dispensed centrally from designated pick-up-points (PuPs). Barriers and facilitators of chronic medicine collection exist at different levels.Aim: To identify barriers and facilitators associated with patients’ characteristics and noncollection of CCMDD patient medicine parcels (PMPs).Setting: The study was conducted at a regional public sector hospital which provides support for 19 primary facilities.Methods: An observational cross-sectional comparative study was conducted.Results: There was no statistically significant difference in collection status in terms of most of the variables compared. Patients who had been on treatment longer or who were receiving multiple items were more likely to collect medication, as were patients with arthritis, HIV and AIDS, but the association was no longer significant after adjusting for other confounders. Patients using internal PuPs were significantly more likely to collect their PMPs than patients using external PuPs, and this may have implications for achieving CCMDD objectives.Conclusion: This study has revealed that recently diagnosed patients are enrolled onto the CCMDD programme whilst the chronic condition stability is not yet attained. Patients were also enrolled onto the programme at the referral facility instead of being down-referred.Contribution: This study makes a case for evaluation research to further assess the CCMDD programme implementation, in order to improve uptake and cost-effectiveness.
Using PhotoVoice to understand mindfulness in health care practitioners
Authors: Osman Iram , Singaram Veena
Published: October 2022

Background: The disruptions of the coronavirus disease 2019 (COVID-19) pandemic have placed added stress on health care practitioners’ (HCPs) mental health. Mindfulness-based interventions (MBIs) have been reported to increase the awareness of burnout and promote self-care practices that enhance mental well-being.Aim: To gain insight into the use of mindfulness through the lens of PhotoVoice on how HCPs reflected on their stressors and sense of self whilst working as frontline workers during the COVID-19 pandemic.Setting: This study was conducted online with HCPs working in South Africa during the first wave of COVID-19.Method: A four-week MBI intervention was implemented using Zoom. An exploratory qualitative analysis was conducted using a PhotoVoice methodology. Interpretative phenomenological analysis was used to generate themes. Fifty-five HCPs consented to participate in this study.Results: The major themes identified were operating on autopilot, feeling a sense of overwhelm because of COVID-19, using faith to cope and being able to attain a sense of self-compassion by the end of the intervention.Conclusions: Using visual representations, HCPs were able to share the development of their reperceived lived experiences of increased self-compassion as they navigated the dilemmas and disruptions of the pandemic.Contribution: A brief online MBI was impactful enough to show a reappraisal of the stressors of COVID-19, such that HCPs felt calmer, more competent and more compassionate. PhotoVoice methodology is recommended for future studies and mindfulness courses. It facilitates a deeper understanding of the practice of imbuing mindfulness and its impact on stressors and the self.

Authors: Ashipala Daniel O. , Shapopi Miina
Published: October 2022

Background: While health services have been offered at various schools in Namibia since independence in 1990, coverage has been limited and there has been a notable decline in recent years. This reduction of services is of great concern, with questions being raised regarding what factors are affecting the provision of these services.Aim: To explore the factors affecting the provision of health services to schools in Engela district, Ohangwena region, Namibia.Settings: Semistructured interviews were conducted at a public health care facility situated in the northern part of Namibia.Methods: A qualitative, explorative, descriptive and contextual research design was utilised. Data were collected through semistructured interviews with 15 nurses from a health centre, of whom five were enrolled nurses and 10 were registered nurses. The data were then analysed thematically.Results: The study revealed three themes: participants’ understanding of school health services; factors affecting the delivery of school health services; and corrective measures for improving the delivery of school health services.Conclusion: The notable decline in health service provision to various schools within the district suggests that there might be factors affecting the provision of school health services, posing a serious challenge to the active implementation of the School Health Programme.Contribution: These findings could be used to make adjustments to the provision of school health services and will also serve as an information baseline to elicit suggestions for future research related to school health services.
Using fuzzy expectation-based programming for inventory management
Authors: Widowati Widowati , Sutrisno Sutrisno , Tjahjana Redemtus H.
Published: October 2022

Background: Order allocation planning and inventory management are two important problems in manufacturing industries that must be solved optimally to gain maximal profit. Commonly, there are several unknown parameters in those problems such as future price, future demand, etc., and this means decision-making support that can handle this uncertainty is needed to calculate an optimal decision.Objectives: This study aimed to propose a newly developed joint decision-making support to solve order allocation planning and inventory optimisation of raw materials in a production system comprising multiple suppliers, products and review times with fuzzy parameters.Method: The model was formulated as a fuzzy expectation-based quadratic programming with the uncertain parameters approached as fuzzy numbers. This was used to handle the fuzzy parameters involved in the problem. A classical optimisation algorithm, the generalised reduced gradient combined with branch-and-bound embedded in LINGO 18.0 was applied to calculate the optimal decision. Numerical experiments were conducted using some randomly generated data with four suppliers, four raw materials and six review times.Results: Results provided the optimal decision for the given problem, that is, the number of raw materials to be ordered from each supplier at each review time, as well as the corresponding number to be stored in the warehouse.Conclusion: The proposed model successfully solved the given problems and thus can be used by decision-makers to solve their order allocation planning and inventory problems.
A comparative analysis of the depiction of queer characters in Hartinger’s Geography Club and Entin’s film adaptation
Authors: Uys Matthys J.
Published: October 2022

Literature is very important when referring to problems experienced by individuals, talking about life and life around individuals. Though interesting and entertaining stories can be told, various forms of stories can stimulate and inspire readers, especially when conveying human values through the means of ‘character’ (Alvinindyta 2018:8, 10). The depiction of fictional characters is a pivotal literary element in exposing and informing a target audience of an identified social issue. Therefore, the fictional characters depicted within literary texts may be used to allow more individuals to become better acquainted with the gender identities that form part of cultures and traditions in heteronormative societies (Uys 2020:3; Uys, Romylos Nel 2021:3; The Other Foundation 2016:23). This article aims to show how Brent Hartinger depicts queer characters in his 2004 queer text Geography Club. Entin’s 2013 film adaptation is also included to carry out a comparative analysis of the novel and the film, adding more depth to the article and broadening the scope. The aim of the investigation on which the article is based was to allow more readers to become better acquainted with gender identities that form part of cultures and traditions in heteronormative societies. A qualitative approach was followed, using hermeneutics as the strategy of inquiry. The conceptual and theoretical framework was queer characters as a queer literary element, whilst the data generation method was document analysis. The main findings were that there are four possible types of queer characters (Cart Jenkins 2006) presented that may be applied to depict fictional characters of a queer literary work, and Hartinger (2004) and Entin (2013) depict their queer characters accordingly to inform readers and possibly change ingrained perceptions of various gender identities.

Published: October 2022

Background: Epilepsy is a chronic and debilitating condition affecting people of all ages in many nations. Healthcare practitioners look for effective ways to track patients’ seizures, and a seizure diary is one of the methods used. This scoping review sought to identify current norms and practices for using seizure diaries to manage epilepsy.Method: A scoping review was performed by screening relevant studies and identifying themes, categories and subcategories.Results: A total of 1125 articles were identified from the database; 46 full-text articles were assessed for eligibility, of which 23 articles were selected. The majority (48%) of the studies were prospective studies. The majority (65%) of the articles were studies conducted in the United States. The themes identified were types of seizure diaries used in clinical practice, contents and structure of a standardised seizure diary, the use and efficacy of seizure diaries in medicine and challenges relating to using a seizure diary for patient management.Conclusion: The study revealed that a seizure diary remains a relevant tool in managing epilepsy. The two forms of diaries in use are electronic and paper-based diaries. The high cost of data and the expensive devices required to access electronic diaries make it unsuitable in a resource-limited setting. Despite its disadvantages, imperfections and inadequacies, the paper-based diary is still relevant for managing patients with epilepsy in resource-limited settings.Contribution: This study reviewed the literature to find the current norms and practices in using seizure diaries. The benefits of the different formats were emphasised.

Pulmonary hypertension and right ventricular function in the sickle cell populace
Authors: Oni Opeyemi O. , Adebiyi Adewole A. , Aje Akinyemi , Akingbola Titilola S.
Published: October 2022

Background

Sickle cell anemia (SCA) is a recognized cause of heart failure and pulmonary hypertension (PHT). However, the effect of PHT of right ventricular (RV) function has not been well elucidated.

Objective

To determine the effect of PHT on RV function in patients with SCA.

Patients and methods

Cases were adults with SCA with PHT. Controls were patients with SCA without PHT. All patients were recruited in a steady state. Echocardiography was done according to the recommendation of the American Society for Echocardiography. Measures of RV function used were RV fractional area change, peak tricuspid annular systolic velocity (S′), and tricuspid annular plane systolic excursion. PHT was estimated from tricuspid regurgitation jet velocities. Mean pulmonary arterial pressures more than 20 mmHg were said to have PHT.

Results

Of 86 patients, 14 had PHT. The mean values of RV systolic function (RV fractional area change, S′, and tricuspid annular plane systolic excursion) were not significantly different between cases and controls. Transtricuspid A was faster, with the E deceleration time shorter in those with PHT. Loud P2, PR interval, and waist–hip ratio (especially in women) correlate directly with PHT, whereas systolic blood pressure, early E deceleration time, and a history of hemolytic crisis correlated inversely with PHT. Systolic blood pressure and loud P2 are independent predictors of PHT in this study.

Conclusion

PHT had a prevalence of 16.3% in patients with SCA in this study. There is no significant effect of PHT on RV systolic function in patients with SCA.

Published: October 2022

Background

During the COVID-19 pandemic, patients with sickle cell disease (SCD) were categorized as a high-risk group, as they might develop a series of life-threatening complications owing to systemic vasculopathy and their modulated immune system. In this review, 20 articles published between December 2019 and January 2021 were included, which reported cases of patients with SCD diagnosed with COVID-19.

Patients and methods

A total of 343 patients with SCD worldwide were included (mean age is 25 years). Overall, 56% of the study population was female. A total of 322 patients had symptoms; 193 patients presented with vaso-occlusive crises and COVID-19 symptoms. Moreover, 15% reported only vaso-occlusive crises symptoms without COVID-19 symptoms. Typical acute chest syndrome symptoms were reported in 27 patients.

Results

Overall, 79% of the population was admitted to hospitals. Blood transfusion was received by 51%, and 23% needed oxygen. Mortality was reported in 18 (5%) patients. The outcome of COVID-19 in patients with SCD did not significantly differ from the general population and seems better compared with the other vulnerable groups.

Conclusion

Proinflammatory status in patients with SCD and frequent use of some medications, such as hydroxyurea, can explain this outcome and could be the reason for reduced COVID-19 complications in patients with SCD. Further molecular studies are needed to understand how SARS-CoV-2 could affect patients with SCD.
Partial Pelviureteric Junction Obstruction Secondary to BK Virus Infection Early Posttransplantation - A Case Report
Authors: Anandh Urmila , Gowrishankar Swarnalata , Aurangabadkar Hrushikesh
Published: October 2022

A 63-year-old female presented to our hospital with progressive allograft dysfunction, declining urine output and fluid overload. She had undergone a second transplant 4 months before. Her evaluation revealed partial pelviureteric obstruction in her ultrasound. She underwent a renal biopsy which revealed BK virus infection. The pelviureteric obstruction improved with oral diuretics and her mycophenolate sodium was discontinued. The case illustrates a rare urological manifestation of BK virus infection which can present with symptomatic allograft dysfunction early posttransplantation.

Published: October 2022

Background:

Due to the scarcity of organs available for transplantation, several patients lose their lives each year. Increased awareness and positive attitudes alone may be insufficient to increase an individual's willingness to donate (i.e., the basic tenets of the knowledge-attitude-practice/KAP model). Therefore, it is pertinent to examine other psychological determinants that are associated with engaging in the altruistic/prosocial act of organ donation.

Objective:

To understand the association between empathy and KAP of organ donation in an Indian population. This pilot is the precursor to a larger project which aims to develop and test an empathy intervention to promote organ donation.

Methods:

Using a cross-sectional design, Indians (N = 419; female = 261; mean age = 28.48 years) aged 18 years and above were recruited using convenience sampling through an online survey. Questionnaires included the Awareness, Attitudes, and Practice of Organ Donation (Chakradhar et al., 2016) and Empathy Quotient-8 (Loewen et al., 2010). Multiple regression analyses were carried out to analyze the data.

Results:

Results showed that empathy was related to: (i) Total KAP (β = 0.123, P = 0.014), and (ii) attitudes (β = 0.195, P < 0.001) towards organ donation.

Conclusion:

These pilot study findings indicate that public health messages focused on evoking empathy can use the technique of patient/donor narratives, and training clinicians on empathic communication skills can help increase individuals' KAP of organ donation. Further, this pilot elucidated the need to conduct mixed-method studies with a donor and nondonor population and clinicians prior to developing and testing a larger empathy-centered intervention aimed at promoting the KAP of organ donation.

Authors: Shailaja B , Javadekar Archana , Chaudhury Suprakash , Saldanha Daniel
Published: October 2022

Objectives:

The objective of this study is to investigate the correlation between the regional gray matter volumes and length of Para Cingulate Sulcus (PCS) with the clinical profile of patients with schizophrenia.

Materials and Methods:

In this hospital-based, cross-sectional study, thirty consecutive in-patients diagnosed with schizophrenia and equal number of healthy volunteers matched for age- and sex- were recruited as controls. Detailed clinical assessment and magnetic resonance imaging (MRI) of the brain were carried out within 2 days for controls and within 2 weeks of hospitalization for patients. The Positive and Negative Syndrome Scale and Montreal Cognitive Assessment were applied to schizophrenia patients to assess symptoms and cognitive function, respectively.

Results:

Schizophrenia patients had significant volume deficit in bilateral amygdalae, bilateral superior temporal gyri, anterior cingulate cortex and bilateral hippocampi, along with a highly significant reduction in the length of right PCS. Schizophrenia patients with the duration of untreated psychosis (DUP) of 6–12 months showed a significantly greater volume of the right superior temporal gyrus (STG). First-episode schizophrenia patients had a significant reduction in the length of the left PCS. The volume of bilateral superior temporal gyri in schizophrenia patients showed a significant direct correlation with positive symptoms and an inverse correlation with negative symptoms.

Conclusion:

Schizophrenia patients have significant volume deficit in some brain regions. DUP of 6–12 months is associated with significantly greater volume of the right STG. First-episode schizophrenia patients have a significant reduction in the length of the left PCS. In schizophrenia patients, the volume of bilateral superior temporal gyri showed a significant direct correlation with the positive symptoms and an inverse correlation with the negative symptoms.

Incubus syndrome is a disorder typically seen in females where she reports that a male demon lies upon her and engages in sexual activity with her. While the concept of incubus is typically based on Western folklore a limited number of case reports are present on this topic more from India. There is a diverse opinion among the authors related to this disorder where some link this to psychotic disorders while some to sleep disorders. Here we report a case series of females who were suffering from psychotic disorder and over time developed incubus syndrome. We also the role of cultural factors and superstition in the formation of these disorders and the role of antipsychotic medication and modified electroconvulsive therapy in its treatment.

Просторовоподібний континуум як фізична реальність Всесвіту
Authors: Карпенко Іван
Published: October 2022

Обґрунтовується, що недосяжний при постійних швидкостях руху просторовоподібний (ПП) континуум Всесвіту є фізичною реальністю при прискорених швидкостях руху. Показано, що такі фізичні феномени як інерція, уповільнення часу та лоренцеве скорочення в спеціальній теорії відносності (СТВ) відбуваються в ПП-світі в процесі прискореного руху тіла і, відповідно, в неінерційних системах відліку. Прискорення інерції – властивість не часовоподібної (ЧП), а просторовоподібної частини континууму. Це властивість порожнього просторово-часового континууму, а саме ПП-континууму, за наявності зовнішніх сил перешкоджати зміні швидкості тіла. Уповільнення часу та лоренцеве скорочення є також наслідком прискореного руху тіла при досягненні ним значення постійної швидкості, тобто відбувається в процесі становлення інерційної системи. У цьому напрямку досліджуються питання доповнюваності рухів у евклідовому і у псевдоевклідовому континуумі, у мова взаємного перетворення часовоподібного (ЧП) стану та ПП-стану континууму. Приведено формульні вирази принципу доповнюваності рухів для евклідового і псевдоевклідового континуумів. Обґрунтовується, що псевдоевклідова геометрія є загальною геометрією реального простору-часу, перш за все тому, що в історії  руху будь-якого тіла так чи інакше було присутнє прискорення. На прикладі евклідового простору демонструється, що перетворення координат Лоренца у геометричному відношенні відіграють роль повороту чотиривимірного світового інтервалу з неподілюваними компонентами простору і часу та є проекцією на систему координат, де ці характеристики розділені і розглядаються як незалежні. Обґрунтовується, що для лоренцевого скорочення мова йде не про реальне скорочення довжини об'єкта, що рухається, а про виміряну довжину непорушним спостерігачем. Щодо уповільнення часу, то відбувається реальне уповільнення часу і саме для об’єкту, що рухався. І відбувається воно лише у неінерційних системах відліку, тобто за наявності прискорення, тобто у ПП-світі. Тому саме властивості ПП-світу визначають феномени уповільнення часу та лоренцевого скорочення. Саме ПП-континуум є відповідальним за феномени СТВ, саме для ПП-континууму були віднайдені перетворення Лоренца і введене поняття псевдоевклідового простору-часу. Тому з повним правом спеціальна теорія відносності може бути названа теорією простору-часу у ПП-світі
