Investigating Employee Green Behavior through Perceived Organizational Support for the Environment in the Hotel Industry
Authors: Chowdhury Dr. Rashid Ahmed , Shamsher Dr. Robaka
Published: May 2023

Purpose - This study investigates the role of perceived organizational support for the environment (POS-E) on employee green behavior (EGB). It also examines the mediating role of employee environmental commitment (EEC) and green work climate (GWC), as well as the moderating role of employee green awareness.
Method - Data were collected from 247 hotel employees located at Cox’s Bazar, Bangladesh applying convenient sampling. Data were analyzed using the structural equation modeling (SEM) technique and SPSS.
Results - Findings reveal that POS-E positively influences EGB while EEC and GWC fully mediate the association between POS-E and EGB. Findings also show that POS-E on EEC and GWC is more significant when employees have greater ecological awareness.
Implications - The findings imply that the hospitality firms’ ecological POS can improve employee green behavior. Empayees’ ecological awareness also plays an important role in such behavior.
Originality – The study contributes to the existing literature in the context of the hospitality industry by filling up the gap in exploring the mechanism through which POS influences employee behavior.
Numerical Simulations of Tidal Deformation and Resulting Light Curves of Small Bodies: Material Constraints of 99942 Apophis and 1I/‘Oumuamua
Authors: Taylor Aster G. , Seligman Darryl Z. , MacAyeal Douglas R. , Hainaut Olivier R. , Meech Karen J.
Published: May 2023

In this paper, we present an open-source software (Simulator of Asteroid Malformation Under Stress, SAMUS) that simulates constant-density, constant-viscosity liquid bodies subject to tidal forces for a range of assumed viscosities and sizes. This software solves the Navier–Stokes equations on a finite-element mesh, incorporating the centrifugal, Coriolis, self-gravitational, and tidal forces. The primary functionality is to simulate the deformation of minor bodies under the influence of tidal forces. It may therefore be used to constrain the composition and physical structure of bodies experiencing significant tidal forces, such as 99942 Apophis and 1I/‘Oumuamua. We demonstrate that SAMUS will be useful to constrain the material properties of Apophis during its near-Earth flyby in 2029. Depending on the material properties, Apophis may experience an area change of up to 0.5%, with similar effects on the photometric brightness. We also apply SAMUS to constrain the material dynamic viscosity of 1I/‘Oumuamua, the first interstellar object discovered traversing the inner solar system. ‘Oumuamua experienced a close approach to the Sun at perihelion (q ≃ 0.25 au) during which there were significant tidal forces that may have caused deformation of the body. This deformation could have lead to observable changes in the photometric light curve based on the material properties. The application of SAMUS to produce synthetic observations which incorporate tidal deformation effects demonstrates that no deformation—an infinite dynamic viscosity—best reproduces the photometric data. While these results indicate that ‘Oumuamua did not experience significant tidal deformation, a sophisticated model incorporating nonprincipal axis rotation is necessary to conclusively analyze both ‘Oumuamua and Apophis.
Cysta Radicularis Magna Maxillae: A Case Report and 5-Year Follow-Up
Authors: Bizevski Danco , Peeva-Petreska Marija , Markoski Nikolce , Bajramov Enes
Published: May 2023

BACKGROUND: An odontogenic cyst is a pathological, epithelial-lined cavity containing fluid or semi-fluid which arises from the epithelial remnants of tooth formation. These cysts may become increasingly obvious clinically as they increase in size, initially creating a bony hard swelling. As this gradually and slowly enlarges, the bony covering becomes increasingly thin, which clinically may be  demonstrated on palpation. Management of jaw cysts as a pathology requires a serious and thorough approach, and it begins at the first examination of the patient. The most important starting point is to analyze and find out the cause of the change, the duration of development, and the presence or absence of clinical symptoms. The use of 3D CBCT analysis of the jawbones provides an answer for the modality of surgical treatment, the proximity to certain anatomical structures, and the way to resolve postoperative bone defects.
CASE PRESENTATION: Twenty-three-year-old male, came with swelling on the left anterior side of the face, and above tooth 22. The swelling began 7 days earlier, and the patient had no other medical conditions and diseases. The radiographic examination shows radiopaque mass  between and above the root of tooth 22 in the anterior maxilla, confluent with other large radiopaque mass to the other teeth of this zone. A radical surgical approach was considered for cyst removal, and bone regeneration techniques for replenishment of the bony defect.
CONCLUSION: A radical surgical approach is the only treatment in most cases of large radicular cysts. It should be noted that the preoperative 3D analysis is also a key factor that dictates this radical approach. Bone augmentation techniques are a reliable and predictable method for filling in bone defects, and should always be combined and included in this treatment.

Laïcités, écoles, intégration
Authors: Mercier Charles
Published: May 2023

La laïcité serait-elle un principe déterminant pour construire une société intégrée ? Du fait des violences qui se justifient par une phraséologie religieuse, la question mérite d’être posée. La réflexion est menée depuis un certain temps dans l’Éducation nationale. Des initiatives sont prises aussi par les jeunes eux-mêmes. Elles montrent que la laïcité n’est pas incompatible avec la reconnaissance de l’autre.
La fraternité au XXI e siècle
Authors: de Vitry Alexandre
Published: May 2023

La fraternité désigne les cercles les plus fermés, les plus combatifs, comme ceux qui sont les plus ouverts ou les plus pacifiques. Après avoir connu un bref âge d’or lors de la révolution de 1848 en France pendant laquelle fut consacrée la devise républicaine, elle connaît une éclipse. Trop irénique pour certains, trop familiale et biologique pour d’autres, la fraternité devient désuète, voire suspecte. Alexandre de Vitry s’interroge sur les conditions de son retour au XXI e  siècle, alors que partout les anciennes solidarités se dégradent.

La mobilisation politique évangélique au Brésil
Authors: Bastian Jean-Pierre
Published: May 2023

Avec la progression de l’évangélisme, l’évolution politico-religieuse du Brésil est spectaculaire. Ce sont surtout les pauvres qui sont attirés par le pentecôtisme. Ils trouvent protection et espoir de progression sociale auprès des pasteurs et dans les communautés. Cette tendance n’est pas sans conséquence sur une vie politique de plus en plus populiste. La situation brésilienne est caractéristique de la culture politique latino-américaine, marquée par un modèle patriarcal et corporatiste.
Ave M.A.R.I.A. : couronnes de fleurs et chapelets de prières dans les Miracles de Nostre Dame de Gautier de Coinci
Authors: Radomme Thibaut
Published: May 2023

Examinant l’essor du Psautier de la Vierge – soit la récitation de 150  Ave Maria comptés sur un chapelet – dans le courant des xii e et xiii e  siècles, l’article rappelle que cette pratique trouve son origine dans deux dévotions antérieures : l’offrande de couronnes de fleurs et la prière répétitive. À l’issue d’un relevé des allusions au Psautier de la Vierge dans les Miracles de Nostre Dame de Gautier de Coinci, l’hypothèse est formulée que le miracle I Mir 23, mettant en scène la dévotion de la Corona gloriosae virginis Mariae , opère pour la première fois en langue romane la synthèse des symboliques numérique et florale à l’origine du Psautier en érigeant le nom de Marie en chapelet symbolique. Mis en perspective avec des pratiques lettristes similaires chez Adgar et chez Guillaume de Digulleville, le miracle I Mir 23 semble à ce titre constituer le plus ancien indice en langue vernaculaire de la formalisation et de la diffusion en cours du Psautier de la Vierge.
Disparitions et réapparitions de la scène psychanalytique : le paradigme Ferenczi
Authors: Gougoulis Nicolas
Published: May 2023

L’auteur pose la question de la disparition et réapparition des figures psychanalytiques en examinant le paradigme de Ferenczi. Il reprend l’histoire du concours de 1922 comme moment central du déroulement du drame. La question posée par Freud de l’articulation de la théorie et de la pratique, n’a jamais été répondu. L’impact de de ce concours inachevé fut le maintien de l’unité de l’Institution au prix a marginalisation de Ferenczi et de Rank. Par la suite l’auteur examine les conditions du retour sur scène des protagonistes oubliés en essayant de définir la possibilité d’en faire une histoire la complexité du phénomène.
Auteurs oubliés. Théorisations méconnues
Authors: Meslem Mustapha
Published: May 2023

August Aichhorn, psychanalyste viennois, oublié ou méconnu, n’ayant écrit qu’un seul livre, a été un novateur en amenant à la psychanalyse des populations qui en étaient exclues : adolescents délinquants, familles, et personnes de catégories sociales n’appartenant pas à la bourgeoisie viennoise. Sa pratique clinique de la psychanalyse, développée dans la revue « pédagogie psychanalytique », va influencer une multitude de psychanalystes. Celles et ceux qui ont participé à ses séminaires vont essaimer sur 2 continents : En Europe avec les polycliniques mais aussi en Grande-Bretagne où ces psychanalystes vont jouer un rôle de médiation dans la controverse entre Mélanie Klein et Anna Freud, et en France où l’ordonnance 1945 sur la protection des mineurs va s’en inspirer.

The educational press and scholarly journals today are swooning over the latest technology, such as virtual reality (VR) or augmented reality (AR), as such tools that have the potential to immerse students into a context-rich environment designed to help them learn by exploring. This chapter will examine how exhibitions and museum engagement help visitors to better relate with the world around them and explore and understand a wide variety of concepts, issues, events, and phenomena. By interacting with the works on display, and with the help of gallery guides and educational programming, visitors learn through in-person, dynamic, and hands-on approaches. The authors will review the literature on the learning theories and the research on the most successful approaches.
Using UX Design Principles When Designing Context-Rich Learning Experiences
Authors: Smith Travis J.
Published: May 2023

To make the most context-rich experiences possible and avoid a myriad of problems, designers must keep a user-centric focus. By viewing our educational products through the perspective of the user, we can devise more accessible, diverse, meaningful, and above all enjoyable experiences. Using simple tools such as problem statements, personas, user maps, story boarding, wireframes, low-definition prototypes, and high-definition prototypes, we can consult users first in design to inform us on how to proceed with decisions. Using the simple outlined in the Design Thinking process of empathizing, defining, ideating, prototyping, and testing, we can deliver the most user centric experience possible. The author will show how Design Thinking couples so well with User Experience (UX), walk through what a user study is, what to do with the feedback you get from users, and how to keep the user in mind from inception to launch. In this chapter, the author will discuss the basic framework of UX, where to apply the tools within the framework and why these tools are important when developing context-rich experiences.

Severe CD8+ T Lymphopenia in WHIM Syndrome Caused by Selective Sequestration in Primary Immune Organs
Authors: Majumdar Shamik , Pontejo Sergio M , Jaiswal Hemant , Gao Ji-Liang , Salancy Abigail , Stassenko Elizabeth , Yamane Hidehiro , McDermott David H , Balabanian Karl , Bachelerie Françoise , Murphy Philip M
Published: May 2023

Warts, hypogammaglobulinemia, infections, and myelokathexis (WHIM) syndrome is an ultra-rare combined primary immunodeficiency disease caused by heterozygous gain-of-function mutations in the chemokine receptor CXCR4. WHIM patients typically present with recurrent acute infections associated with myelokathexis (severe neutropenia due to bone marrow retention of mature neutrophils). Severe lymphopenia is also common, but the only associated chronic opportunistic pathogen is human papillomavirus and mechanisms are not clearly defined. In this study, we show that WHIM mutations cause more severe CD8 than CD4 lymphopenia in WHIM patients and WHIM model mice. Mechanistic studies in mice revealed selective and WHIM allele dose-dependent accumulation of mature CD8 single-positive cells in thymus in a cell-intrinsic manner due to prolonged intrathymic residence, associated with increased CD8 single-positive thymocyte chemotactic responses in vitro toward the CXCR4 ligand CXCL12. In addition, mature WHIM CD8+ T cells preferentially home to and are retained in the bone marrow in mice in a cell-intrinsic manner. Administration of the specific CXCR4 antagonist AMD3100 (plerixafor) in mice rapidly and transiently corrected T cell lymphopenia and the CD4/CD8 ratio. After lymphocytic choriomeningitis virus infection, we found no difference in memory CD8+ T cell differentiation or viral load between wild-type and WHIM model mice. Thus, lymphopenia in WHIM syndrome may involve severe CXCR4-dependent CD8+ T cell deficiency resulting in part from sequestration in the primary lymphoid organs, thymus, and bone marrow.

Growing resilience capacity for learners presenting with specific learning disability in learners with special education needs schools
Authors: Mawila Daphney
Published: May 2023

Background: Preventing adversity from accelerating among learners with specific learning disabilities (SLD) is imperative. Continuous adversities, such as social-emotional, psychological and academic difficulties, characterise learners with SLD. Prior studies have been conducted on learners with SLD developing a disorder because of the difficulties they face. However, very few studies offer evidence of how learners presenting with SLD cope despite their learning disability.Objectives: The study sought to investigate what resilience resources are available among learners with SLD in learners with special education needs (LSEN) schools and to provide stakeholders with evidence of resilience enablers for learners with SLD.Method: An exploratory quantitative research study was adopted, and 217 respondents with SLD were selected through purposive sampling in four LSEN schools. These learners completed the Child and Youth Resilience Measure (CYRM-28). Data were analysed using the Statistical Package for the Social Sciences (SPSS) and the custom table was used as a statistical techniqueResults: Even though the presence of SLD negatively affects an individual’s academic, psychological, social and emotional functioning, the results of this study show that individual qualities, relationships with caregivers and peers and contextual resources were resilience-enabling resources for learners with SLD.Conclusion: The study’s results show that the combination of individual attributes, relational and environmental factors enables the resilience of learners with SLD. When given accessible and meaningful support, learners with SLD can develop resilience.Contribution: The study contributes to the dearth of knowledge regarding the resilience of learners with SLD in LSEN schools.
Practitioner perceptions about optometric networks in South Africa
Authors: Maluleke Simon A. , Moodley Vanessa R.
Published: May 2023

Background: Private healthcare in South Africa is largely financed by medical schemes. Optometrists reluctantly contract with administrators and networks to service these patients, despite them feeling networks are undesirable and exploitative. Networks contend that various mechanisms employed are necessary to ensure sustainability and prevent fraud, wastage and abuse. A working relationship between practitioners and networks should ideally be cordial and appreciated by each party as being mutually beneficial to the success of their respective businesses.Aim: To assess practitioners’ knowledge and perceptions regarding optometric networks.Setting: The study was conducted amongst optometric professionals in the private sector in South Africa.Methods: A descriptive, mixed-method study was conducted using a semi-structured questionnaire. Interviews with senior personnel from the networks were conducted.Results: Approximately 77% of respondents belonged to networks with 91% being knowledgeable about networks and their role within optometry. Opticlear had 72% members, while Iso Leso and preferred provider negotiators (PPN) had 67% and 41%, respectively. Most optometrists (69%) neither believed in the need for networks nor that they provide value to the profession, while 94.7% joined networks merely to receive direct payment and access patients, with no other benefits noted.Conclusion: Practitioners reluctantly contract to networks for direct payment and to access patients. Furthermore, practitioners feel that networks bully and victimise them while networks highlight their responsibility to reduce healthcare costs and negative practices of fraud, waste and abuse.Contribution: Providing sustainable, cost-effective and quality eye care services requires collaboration between networks and practitioners and appreciating each other’s roles in the delivery of eye care services.

An introduction to insulin use in type 2 diabetes mellitus
Authors: Coetzee Ankia
Published: May 2023

The benefits of the newer antidiabetic agents available for managing type 2 diabetes mellitus (T2DM) remain indisputable, but many patients will require insulin therapy in the disease course. Given the limited access to newer antidiabetic agents, insulin remains a standard treatment modality in T2DM in South Africa. Early, multifactorial intervention remains ideal, but glucose, blood pressure and cholesterol values remain above target in many countries. Barriers to achieving glucose control in South Africa include the healthcare provider’s being unfamiliar with the practicalities of insulin administration, initiation and titration. This article highlights these gaps and offers pragmatic solutions to overcome them.
RSCL onto-epistemology and practice approach to reconceptualise responsible leadership theory
Authors: Ntakumba Stanley S. , De Jongh Derick
Published: May 2023

Purpose: This article explores how the relational social constructionist leadership (RSCL) ontology and epistemology, as well as the practice approach, could be employed to reconceptualise the responsible leadership theory.Design: This paper presents a literature review on the responsible leadership and relational leadership theories. It also reviews literature on the RSCL onto-epistemology as its theoretical framework and the practice approach as its methodology. The empirical analysis that is underlined by the abductive mode of enquiry is based on nine interviews with leaders from the Twende Mbele (TM) African Partnership for Monitoring and Evaluation.Findings: The findings comprise one main theme (relational leadership practice of interest) called identifying. Identifying constitutes five sub-themes (intersecting relational leadership practices): context identity, gender identity, government identity, language identity and champions identity. Recommendations to reconceptualise responsible leadership theory are based on the discussion of the findings.Practical implications: The findings could enhance the quality, intentionality and practicality of inter-organisational leadership stakeholder engagement strategies. The social construction of leaders as role models, in the form of cultivating their identity as champions beyond the internal positional leaders, could be practiced by business leaders in other organisational settings to champion social-relationality and ethics-orientation in society in line with the core tenets of responsible leadership theory.Originality/value: The RSCL onto-epistemology and the practice approach methodology provide conceptual tools to advance responsible leadership theory from a leader-centric focus to the collective domain of leadership research by using leadership practices as the unit of analysis.

Published: May 2023

Background: The number of children with autism spectrum disorder (ASD) is rapidly increasing globally and requires a supportive educational system to meet the needs of these children.Aim: The study assessed challenges faced by teachers of children with ASD in the public special schools of the Limpopo province, South Africa.Setting: The study was conducted in seven public special schools in the Limpopo province, South Africa.Methods: Face-to-face semistructured interviews were conducted with 12 teachers regarding the challenges they face in educating children with ASD. Tesch’s inductive, descriptive open coding technique enabled the researcher to analyse and report, subthemes that emerged from this qualitative explorative and descriptive data. Measures to ensure trustworthiness and ethical considerations were carried out throughout the study.Results: Analysis of the interviews revealed that the structure and systems of special schools do not support the educational needs of children with ASD. The strategic plans and policy framework on inclusive education are not being executed adequately. Learning for ASD children is not supported because of substandard infrastructure, curricula, lack of teaching material, health practitioners, unbalanced teacher–learner ratio, inadequate staff skills, school culture, shared beliefs and lack of management support.Conclusion: The study revealed challenges faced by special education teachers indicating the influence on the provision of high-quality education to children with ASD. The Department of Basic Education at the national level should monitor all special schools regularly, provide the necessary support and ensure that the complex needs of children with ASD are met.Contribution: The study contributes to understanding of the challenges faced by teachers of children with ASD in providing high quality of education and affirm sound basis of advance information to monitor and evaluate the education of children with ASD in special public schools, which is within the scope of the journal.

Authors: Botha Doret , Van Dijk Gerda , Marais Amori
Published: May 2023

Orientation: Globally, the repercussions of the coronavirus disease 2019 (COVID-19) pandemic infiltrated many areas within societies. Like all other institutions, higher education institutions (HEIs) had to migrate to online and blended activities, and work-from-home (WFH) became characteristic of the ‘new normal’.Research purpose: The main purpose of the study was to determine the perspectives on work engagement and WFH among employees of an HEI in South Africa during the global COVID-19 pandemic.Motivation for the study: There is limited published research reporting on WFH and work engagement in HEIs.Research approach/design and method: The study employed a quantitative-based cross-sectional design. The target population of this study included all employees an HEI in South Africa who worked from home during the COVID-19 lockdown. A web-based survey was used to collect the data. In total, 399 respondents participated in the research.Main results: The results of the study revealed that the employees were to a great extent engaged in their work because of the organisational support received from the institution. It was also evident that some employees experienced difficulties with establishing a work routine, a lack of sufficient equipment and resources to function at home, work–home interference, increased workload and working hours, isolation and work–life balance issues.Practical/managerial implications: The results of the study are important to inform business decisions regarding the WFH model as an alternative working arrangement to be considered in HEIs.Contribution/value-add: This study contributes to the body of knowledge regarding work engagement and WFH in HEIs in the context of the global COVID-19 pandemic.

Authors: Lesebo Thabo J. , Rambe Patient , Ndofirepi Takawira
Published: May 2023

Background: The extensive utilisation of mobile technologies (MTs) for cost reduction and improving organisational efficiency is widely acknowledged in the entrepreneurship literature. Despite the fact, the effect of adopting MTs on the managerial competencies of small, micro and medium enterprises (SMMEs) remains incomprehensible by emerging construction firms (ECFs).Objectives: This study contributes to the theory and practise of competency development in project management (PM) by exploring how MT adoption intensity during project execution affects the perceived managerial competencies of owners/project managers of ECFs.Method: This quantitative study employed the perspectives of 222 ECF owners/managers surveyed in the Free State province of South Africa. It established how the adoption of MTs during project execution impacted the perceived managerial competencies of these entrepreneurs.Results: The results indicated that the adoption of MTs during project execution has a positive and significant effect on the communicative and social competencies of ECF owners and managers, with MT adoption explaining 88.0% of the variance in communicative competencies and 87.9% in social competencies. The results further demonstrate that the type of device used (laptops and tablets) moderated the strength of the MT adoption – managerial competencies relationship.Conclusion: The study recommends targeted and strategic wider rollout of specific MTs that improve managerial competencies to optimise the efficiency of project-related operations.Contribution: The article contributes to the broader PM theory and literature especially competency-based project execution by exploring how MT adoption can facilitate greater communication and social competencies that improve the organisational efficiency of ECFs.

Outcomes of breast conserving therapy: Recurrence, imaging findings and histological correlation
Authors: Sondezi Marara N. , Buccimazza Ines , Madlala Ntombizakhona B.
Published: May 2023

Background: Breast conserving therapy (BCT) is the mainstay therapy in patients with early breast cancer and selected patients with locally advanced breast cancer. No formal audit has been performed on BCT at our institution.Objectives: To determine the incidence and risk factors for ipsilateral breast tumour recurrence (IBTR). Study the imaging features of IBTR. Determine adherence to the proposed annual mammographic surveillance schedule.Method: Clinical, radiological and histopathological records of patients who underwent BCT from 01 January 2011 to 31 December 2015 were reviewed. Patients were followed up for at least 5 years.Results: Ninety-two patients were included in the study with a mean age of 54.3 years. Eighty of the 92 (87.0%) patients were imaged within 1-year post-BCT. Ipsilateral breast tumour recurrence was 6/92 (6.5%) with mean time to IBTR of 34.4 months. One of the 92 (1.0%) patients had a contralateral metachronous recurrence with no IBTR and 11/92 (12.0%) had distant metastases only. Pathological tumour size and extent (pT2) (68.5%) and pathological lymph node (pN0) (65.2%) were the most common locoregional staging. Infiltrating ductal carcinoma was the most common histological type (88%). Age 35 years was associated with breast cancer recurrence (p  0.01). Imaging findings of recurrence were microcalcification (odds ratio [OR]: 4), asymmetric density (OR: 4) and skin thickening (OR: 2.5).Conclusion: The occurrence of IBTR following BCT in our unit is acceptable and comparable to local and international units. The accuracy of assessing the post-BCT breast for IBTR is in keeping with international standards.Contribution: Improved radiological imaging interpretation of the post-BCT breast.
“They're Not My Children” – A Case Series of Capgras Syndrome in Depression, a Rare Occurrence, and a Missed Diagnosis
Authors: Bhardwaj Akansha , Yadav Jagriti , Singh Priti , Gupta Rajiv
Published: May 2023

Capgras syndrome is a psychopathological phenomenon which is defined under the broad category of “Delusional misidentification syndromes.” It is seen in a wide range of psychiatric and neurological disorders. In the psychiatric literature, Capgras syndrome is most commonly seen in association with schizophreniform psychosis. Here, we report the two cases of severe depressive disorder with psychotic symptoms presenting as Capgras syndrome, leading to significant socio-occupational and biological dysfunction. The case series highlights the need for the early identification of depressive symptoms and timely intervention in patients presenting with Capgras syndrome as it carries high risk of harm to self and others.
Road Rage and Driver Anger-An Indian Perspective
Authors: Mudgal Varchasvi , Niranjan Vijay , Rastogi Pali , Jain Priyash
Published: May 2023

Background and Aim:

Road rage is a term often used to describe driving usually extreme in nature. There seems to be a multifactorial relationship between the situational characteristics of an anger-provoking road situation and the consequent feelings of anger and road behavior. We focus on the dynamics of road rage and the current study pioneers to understand road rage and its correlates in Indian drivers.

Materials and Methods:

An internet based cross-sectional study was done involving 282 participants in India. The 33-item Driving Anger Scale was used to measure driving anger. Data were collected between January 2019 to April 2019. Anger assessment was done using the Deffenbacher Driver Anger Scale.

Results:

Significant driver anger exists among Indian drivers; with males reporting higher driver anger for situations involving police presence, while females reporting higher anger for hostile gestures and discourtesy situations, two-wheeler drivers displayed higher anger in illegal and slow driving situations.

Conclusion:

Our study reports high anger among Indian drivers and indicate that road rage is multifactorial. Stringent checks must be placed as a prerequisite for acquiring a driving license and the devils of road rage must be curbed through intensive awareness campaigns specific to vehicle type, car-pool incentivization, and public participation.

Authors: Pala Vinay , Patil Chidanand , Nagmoti Mahantesh B. , Dalal Anita , Mane Arati
Published: May 2023

Background and Aim:

Human papillomavirus (HPV) infection is the established cause of cervical cancer. There is sparse literature with regard to HPV infection from the southern Belagavi region of India. This study was aimed to detect the HPV genotype distribution, the associated risk factors, and relation with cervical precancerous lesions among HIV-infected women from Belagavi, India.

Materials and Methods:

In this prospective observational study, a total of 214 HIV-infected women aged 18–45 years were recruited. Cervical samples were subjected to the Roche Linear Array assay for HPV detection and genotyping. Cervical status was determined by composite assessment of cytology, colposcopy, and histology. Data were analyzed using Software R version 3.6.0.

Results:

Of the 197/214 women with the adequate cervical sample, 86 (43.6%) were HPV positive, and 111 (56.3%) were HPV negative cases. A total of 132 (69.1%) women had normal cervical status, 26 (13.6%) had CIN1 lesions, 1 (0.5%) had CIN2 lesions, and 12 (6.3%) had CIN3 lesions. Single HPV infection was detected in 47 (54.6%) women and multiple (≥2) HPV genotypes were detected in 39 (45.3%). The HPV genotypes detected in descending order of frequency were HPV 16, HPV 33, HPV 35, HPV 52, and HPV 58. Ever pregnant (parous) women were 4.47 more likely to have HPV infection.

Conclusion:

A high prevalence of HPV infection, with a wide diversity of HPV genotypes and a greater prevalence of HPV 16 among HIV-positive women from Belagavi, India, was observed. Parity was the independent factor associated with HPV detection.

Authors: Wazir Sumaira , Zargar Mohammad Afzal , Muzamil Muhammad , Rashid Fouzia
Published: May 2023

Background and Aim:

Various studies have reported an association of hematological parameters such as red blood cell (RBC), hemoglobin (Hb), hematocrit (HCT), white blood cell (WBC), and platelets with metabolic syndrome (MS) in many parts of the world. However, the association of these parameters with MS in terms of gender has not been elucidated particularly in the ethnic population of northern India. Thus, the study aimed at exploring the association of these hematological parameters with MS stratified by gender in the Kashmiri region of India.

Materials and Methods:

A total of 400 people were enrolled in this study consisting of 204 men and 196 women. MS was diagnosed by the International Diabetes Federation criteria. For statistical analysis, SPSS software and Pearson Partial coefficient analysis were used.

Results:

The prevalence of MS was (50.6% vs. 20.6%) in women and men. WBC and platelets were significantly increased in men with MS (P ≤ 0.05). RBC, Hb, HCT, and platelets were significantly increased in women with MS (P ≤ 0.05). Furthermore, in men, WBC and platelet count increased with the increasing number of MS components. Whereas, in women RBC, Hb, HCT, and platelet count increased with the increasing number of MS components (0, 1, 2, and ≥3).

Conclusion:

MS was more widespread in women than men than women. The association of hematological parameters differed between the genders. WBC and platelets were found to be the risk factors in men and RBC, Hb, HCT, and platelets were found to be the risk factors in women for MS. These hematological parameters could be used for assessing the risk of MS on the basis of gender.

Published: May 2023

Background and Aim:

Phosphoglucomutase 1 (PGM1) is an enzyme that catalyzes the key step that links glycogen synthesis with glucose metabolism. Single nucleotide polymorphism (SNP) (rs11208257) is a functional variant in the PGM1 gene that codes for this enzyme. Impaired glycogen synthesis is linked to type 2 diabetes mellitus (T2DM). Whether this translates into an association between SNP rs11208257 and T2DM is not known. We evaluated the association between the PGM1 gene variant (Y420H; c. 1258 T > C; rs11208257) and T2DM.

Materials and Methods:

We carried out a case-control study by including 225 T2DM patients and 225 age and gender-matched healthy controls. SNP rs11208257 was genotyped by a polymerase chain reaction-restriction fragment length polymorphism method.

Results:

Minor allele frequency was 45% in T2DM patients and 30% in healthy individuals (P = 1.4 × 10-2; Odds ratio = 1.6). The genetic model analysis showed the highest odds ratio for the additive effect of the risk allele.

Conclusions:

The results show that SNP rs11208257 in the PGM1 gene is associated with the risk of T2DM. This association underlines the importance of the glycogen pathway in the pathophysiology of T2DM.

Background

Determining the clinical features and outcomes of patients diagnosed with coronavirus disease 2019 (COVID-19) is fundamental to improve the understanding and adequate management of the novel illness. This study aims to identify the determinants of survival and the outcome within 30 days in hospitalized patients with COVID-19 infection in Upper Egypt.

Patients and methods

A total of 1064 cases were consecutively admitted to isolation hospitals in Upper Egypt. All cases had confirmed COVID-19 infection. The electronic records of the patients were retrospectively revised and the demographic data, clinical manifestations, quick sequential organ failure assessment (qSOFA) score on admission, and 30-day outcome (ICU admission, death, recovery, or still in hospital) were analyzed. Overall cumulative survival rates in all patients and those more than or less than 50 years were calculated.

Results

Overall, 49.2% of the study population were males, whereas 50.8% were females, with mean age of 49.4±17.8 years. On admission, 83.9% were stable with qSOFA score less than 1, 3% required noninvasive mechanical ventilation, and 2.1% required O2 therapy. Within 30 days, 203 (19.1%) cases required admission to ICU. Death was recorded in 11.7% of cases, 28.7% recovered, and 59.7% were still under treatment. Determinants of ICU admission and survival in the current study were age more than 50 years, qSOFA more than 1, and need for O2 therapy or noninvasive ventilation. The cumulative survival was 75.3%, with the mean survival of 28.1, and 95.2% overall survival rate was recorded in those aged less than or equal to 50 years.

Conclusions

Age older than 50 years old, those with preexisting diabetes mellitus, initial qSOFA score, requirement for O2 therapy, and noninvasive ventilation from the first day of hospital admission may be associated with unfavorable 30-day in-hospital outcome of COVID-19.
Role of capnography in detecting hypercapnic events during weaning from mechanical ventilation
Authors: Mansour Mona , Elmekawy Fatma A.M. , Diab Haytham S.
Published: May 2023

Background

End-tidal carbon dioxide (ETCO2) measurement is more applied in clinical practice, as it is a noninvasive tool that helps to evaluate the ventilatory status of the patient. The aim of the present study was to investigate the relationship between ETCO2 and arterial partial pressure of CO2 (PaCO2) measurements and to estimate the role of capnography during weaning off mechanical ventilation.

Patients and methods

A prospective cross-sectional study was conducted on 60 adult critically ill patients with respiratory failure, comprising 47 males and 13 females. They were put on mechanical ventilation, and after fulfilling criteria of weaning, they were kept on continuous positive airway pressure (CPAP) mode for 1 h. ETCO2, PaCO2, and gradient were measured before and after weaning.

Results

Mean difference between PaCO2 and ETCO2 before weaning was 8.3 and after one hour on CPAP was 5.1. There was a highly statistically significant positive correlation between ETCO2 and PaCO2 before weaning and after 1 h on CPAP. Bland-Altman comparison between ETCO2 and PaCO2 before weaning and after 1 h on CPAP revealed limits of agreement were 1.941 to 14.826 and −4.134 to 14.367, respectively.

Conclusion

ETCO2 measurement gives a proper estimation of PaCO2 in patients on mechanical ventilation. ETCO2 decreases the need for repeated invasive arterial blood gas samples.
Optimal pressure in obstructive sleep apnea
Authors: Galal Iman , Diab Haytham S.
Published: May 2023

Background

The prescription of equation-based predicted pressure (Ppred) using mathematical equations has been proposed as a practical strategy for the determination of effective positive airway pressure (PAP). This study aimed at comparing the differences between therapeutic pressures obtained by auto-titrating positive airway pressure (APAP) and 10 predictive mathematical equations among Egyptian patients with obstructive sleep apnea (OSA).

Patients and methods

A retrospective cross-sectional study included 25 PAP-naïve patients (23 males and two females) with polysomnographically confirmed OSA. The 95th percentile pressure (P95) of an APAP device during an attended successful titration study was selected as the effective reference PAP, against which PPred calculated from ten predictive equations was compared.

Results

Among the 25 patients included, four patients had mild, eight had moderate, whereas the remaining 13 patients had severe OSA. The mean P95 was higher than all predictive equations. A total of 24 (96%) of the 25 included patients experienced acceptable air leak during APAP titration. P95 correlated significantly and positively with pressures calculated by most of predictive equations except for those of equations 2, 6, and 7. Comparison between P95 and Ppred showed nonsignificant statistical difference for pressure calculated by Sériès equation, whereas Ppred of other equations were significantly lower than P95. Mean pressure difference between P95 and Ppred was around three in most of the equations with Sériès equation carrying the least mean pressure difference (0.7 cmH2O).

Conclusion

P95 is higher than Ppred, yet Sériès equation was the closest to P95. The utility of predictive equations for determining effective PAP level can serve a beneficial role during titration studies and can be used with caution as a practical alternative for PAP titration.

Context

The number of tuberculosis (TB) patients and multidrug-resistant species of Mycobacterium tuberculosis are increasing worldwide. Effective treatment is still the key factor to control TB in the society.

Aims

The aim of the study was to compare the efficacy of fixed-dose combination (FDC) and separate drug (SD) in the treatment of TB.

Settings and design

The study was a randomized, clinical trial carried out on 331 smear-positive TB patients in the Golestan province, Iran.

Patients and methods

Diagnosis and monitoring method was direct observation of sputum smears under a light microscope, which was used at the end of the second, third, fourth, fifth, or sixth months during the treatment.

Statistical analysis

used Sputum smear conversion rate at the end of second months and therapy outcome at the end of the treatment period were compared in both groups of the study by using the Poisson regression model and calculation incidence rate ratio.

Results

Sputum smear conversion rate at the end of the second month of the treatment had no significant difference between two groups. Success rate at the end of the treatment period was 89.36% in the intervention group and 95.65% in the nonintervention group which had significant difference (P=0.03). Adverse event incidence rate was 5.44% in all studied cases during the period of treatment. It had significant difference between the group who received FDC (8.93%) and the other who received SD (1.86%).

Conclusion

SD had better efficacy than FDC drugs in the treatment of TB patients.
