Authors: Alvarez-Saavedra Valentina , Levasseur Pierre , Seetahul Suneha
Published: April 2022

À partir de données longitudinales sur la population indienne, nous estimons la façon dont l’accroissement des discriminations envers les femmes affecte leur santé nutritionnelle. Tandis que certaines formes de discriminations en Inde se sont détériorées sur la période étudiée, nous observons systématiquement des effets non linéaires de ces changements sur l’état nutritionnel des femmes, suggérant la concomitance de différents mécanismes ayant des conséquences nutritionnelles diamétralement opposées (prise de poids versus perte de poids).

Effect of Psychological Intervention on Perceived Stress and Positive Psychological Traits Among Nursing Students: Findings During the COVID-19 Pandemic
Authors: Wang Wei , Mei Songli
Published: April 2022

High levels of perceived stress and deterioration of positive psychological traits concomitant with the coronavirus disease 2019 pandemic have endangered the health and academic achievement of nursing students. Effective intervention research in this area should be performed as soon as possible. In the current study, a 15-month trial involving nursing students recruited from a medical university was conducted, in which an experimental group (
n
= 126) received the Three Good Things exercise based on social network groups. Two follow ups were performed. There was no intervention in the control group. During the intervention period, there were significant differences in perceived stress, self-efficacy, resilience, and optimism between the two groups (
p
< 0.05). Perceived stress in the experimental group was significantly reduced throughout the follow-up period (
p
< 0.001). Postintervention analysis of optimism showed maintenance of the improvement trend over a 3-month period (
p
< 0.01). There was no significant difference in hope between groups. The Three Good Things exercise had a short-term effect on decreasing perceived stress and increasing optimism among nursing students. [

Repeatability and Comparison of Corneal Tomography in Mild to Severe Keratoconus Between the Anterior Segment OCT MS-39 and Pentacam HR
Authors: Seiler Theo G. , Mueller Maya , Mendes Baiao Tiago
Published: April 2022

PURPOSE:

To detect keratoconus progression, accuracy of tomographic measurements is crucial. The impoved axial resolution of optical coherence tomography (OCT) compared to Scheimpflug photography serves as the motivation to investigate and compare the repeatability of the anterior segment OCT MS-39 (CSO) to Pentacam HR (Oculus Optikgeräte GmbH) in patients with keratoconus.

METHODS:

One hundred twenty-three eyes of 123 patients with keratoconus were enrolled and subdivided in four groups by maximum keratometry (Kmax): Kmax < 48.00 diopters (D), Kmax of 48.00 to 53.01 D, Kmax of 53.00 to 58.00 D, and Kmax > 58.00 D. Three consecutive measurements per eye were acquired with the MS-39 and compared to the Pentacam HR. Kmax, thinnest pachymetry, anterior asphericity, and posterior elevation data were compared. Within-subject standard deviation (S
w
), coefficient of variation (CoV), test–retest repeatability (TRT), and the intra-class correlation (ICC) were calculated and evaluated. Bland–Altman plots were also analyzed.

RESULTS:

The Pentacam HR measures significantly higher Kmax values than the MS-39, with a more pronounced difference for severe cases of keratoconus (0.57 D for all cases; 1.88 D for cases with Kmax > 58.00 D). Thinnest pachymetry was approximately 5 µm thinner when measured by the Pentacam HR than the MS-39, independently of keratoconus stage. A further progressed keratoconus stage was significantly associated with increased measurement errors and resulted in worse repeatability (Kmax < 48.00 D: S
w
= 0.18 D, TRT = 0.50 D, CoV = 0.39%, ICC = 0.989; Kmax > 58.00 D: S
w
= 0.53 D, TRT = 1.48 D, CoV = 0.90%, ICC = 0.984). The behavior was similar for other tomographic parameters.

CONCLUSIONS:

The Pentacam HR and the MS-39 have an overall good agreement for keratoconus; however, the Pentacam HR measures steeper and thinner than the MS-39. The association between the magnitude of topographic and tomographic parameters and their measurement errors suggests that the diagnosis of keratoconus disease progression should be based on the stage and the test-retest repeatability rather than on a fixed value (eg, 1.00 D).

Limit behaviour of constant distance boundaries of Jordan curves
Authors: Qu Feifei , Wei Xin
Published: April 2022

For a Jordan curve $ \Gamma $ in the complex plane, its constant distance boundary $ \Gamma_ \lambda $ is an inflated version of $ \Gamma $. A flatness condition, $ (1/2, r_0) $-chordal property, guarantees that $ \Gamma_ \lambda $ is a Jordan curve when $ \lambda $ is not too large. We prove that $ \Gamma_ \lambda $ converges to $ \Gamma $, as $ \lambda $ approaching to $ 0 $, in the sense of Hausdorff distance if $ \Gamma $ has the $ (1/2, r_0) $-chordal property.
Global stability of local fractional Hénon-Lozi map using fixed point theory
Authors: Ibrahim Rabha W. , Baleanu Dumitru
Published: April 2022

We present an innovative piecewise smooth mapping of the plane as a parametric discrete-time chaotic system that has robust chaos over a share of its significant organization parameters and includes the generalized Henon and Lozi schemes as two excesses and other arrangements as an evolution in between. To obtain the fractal Henon and Lozi system, the generalized Henon and Lozi system is defined by adopting the fractal idea (FHLS). The recommended system's dynamical performances are investigated from many angles, such as global stability in terms of the set of fixed points.
Flipped Classroom Real-World Activities for Learning Open Computing Concepts
Authors: Bosnić Ivana , Čavrak Igor , Van Loenen Bastiaan
Published: April 2022

Various “open” concepts in Computing, such as open standards, open data, open licenses or system interoperability are becoming more important in the professional lives of software engineers. However, students usually do not receive a systematic education about these concepts; rather they sporadically learn about a subset of these topics. This paper presents the revised version of the Open Computing course in the University of Zagreb, Faculty of Electrical Engineering and Computing (FER), which teaches a clear set of current topics focused on open data and correlating concepts. The new e-learning course is carried out using the “flipped classroom” educational method; students construct their knowledge in a set of real-world mini-activities throughout the course, instead of passively learning from the official course resources. In this paper, we discuss our flipped classroom activities, their relation to revised Bloom’s taxonomy of educational objectives, and present the evaluation of the first course instance using this model. Students’ feedback shows they welcome this change in approach, finding the course useful and interesting, and preferring this method to the traditional full lecture setting.

Authors: Wickey da Silva Garcia Fabrício , Ronaldo Bezerra Oliveira Sandro , Da Costa Carvalho Elielton
Published: April 2022

Computer programming subjects have high failure rates, their contents are of great importance for the formation of undergraduate students, however their learning is considered challenging. There are several studies in the specialized literature that investigate the use of types of intervention that can improve the learning of contents, most of them are focused on introductory subjects such as algorithms, considering that it provides the basis for the development of necessary skills and competences for the computer programming. By establishing a solid foundation in the learning of programming contents, through the algorithms subject, it is expected that students will have less difficulty in absorbing the knowledge needed to deepen their programming skills in subsequent subjects. In this sense, the use of approaches that promote active learning on the part of students in algorithmic subjects stand out in the specialized literature, in order to increase their engagement and awaken their interest in the contents covered, making them protagonists of their learning. Thus, the objective of this work is to discuss and analyze the results of an experiment that consisted in the application of a teaching plan that makes use of multiple active methodologies (Virtual Learning Environments, Coding Dojo, Gamification, Problem Based Learning – PBL, Flipped Classroom and Serious Games) in an algorithms subject. We sought to evaluate the learning gains of the proposed approach compared to teaching using the traditional teaching method. A statistical analysis was performed using the Student-t two-tailed approach for independent samples, which showed significant statistical gains when using the proposed approach.

Following adoption of the Moroccan educational system with a blended learning approach vis-à-vis the circumstances of the Covid-19 pandemic, which requires an adaptation on the part of the pedagogical actors to ensure pedagogical continuity and support students to guarantee their academic success. Our aim is to bring students to develop their own self-learning strategies to cope with the demands of the current situation through the use of a digital textbook in a flipped classroom. The sample consists of 362 students of which 54.14% are middle school students and 26.24% are male for the middle school and 23.2% in the high school. The digital textbook and the flipped classroom can improve the acquisition of disciplinary knowledge and obtain better results in students, and they can develop their soft skills. While there is a significant relationship between the development of soft skills in students and their academic success. The student ‘self-learning method using the digital textbook and the flipped classroom can help develop certain soft skills in the student. To conclude, our method remains effective and relevant, and does not replace face-to-face teaching, but is a complement for the teacher to improve his or her professional practices.

Published: April 2022

Purpose: Routine electroencephalogram (EEG) examinations uses intermittent photic stimulation (IPS) for investigation of the visual cortex EEG responses during resting time. This study aimed to discover brain dynamics effects of IPS in 28 generalized epilepsy patients and 28 healthy subjects. Methodology: Signal processing techniques were used in feature extraction by Fast Fourier transform (FFT), feature dimension reduction by t-test (significant, p<0.05) and classification by nearest neighbor (k-NN) and support vector machine (SVM). Results: The epilepsy group had higher level of amplitude in Theta waves compared to the healthy group. The Alpha waves in the resting time and for all IPS frequencies were observed with lower level of amplitude in healthy subjects compared to the epilepsy group. The k-NN (85.7% accuracy) classifier had the best discrimination of epilepsy from healthy group for resting time versus during IPS at 18 Hz IPS. However, using SVM (75.0% accuracy), IPS at 25 Hz yielded the best discrimination between resting time versus IPS in epilepsy where the healthy group responded similarly in all IPS frequencies. Conclusions: This study shows that IPS at 18 Hz and 25 Hz are suitable IPS frequencies for k-NN and SVM, respectively, to discriminate non-photosensitive generalized epilepsy from normal subjects during interictal.

Published: April 2022

The tibial insert conformity is one of the essential parameters concerned with the contact stress distribution of biomechanics characteristics in total knee arthroplasty (TKA). This study aimed to evaluate the effect of tibial insert conformity design on contact stress distribution using Finite Element (FE) analysis. The three-dimensional (3D) FE model of the posterior stabilized type of TKA was analyzed according to the standard knee implant loading. The 3k factorial experimental design was performed for the response surface of different insert curvatures consisting of the curve, partial flat, and flat insert conformity in sagittal and coronal planes. According to the result, the coronal and sagittal plane conformity displayed the effect of the change on the contact stress, including the contact area for the flexion angle of the knee joint. The maximum contact stress increased while the contact area value decreased during the flexion angle of the knee joints raised. The changing insert conformity value in the sagittal plane displayed higher sensitivity to contact stress than the changing conformity in the coronal plane. The relationship between the contact stress and tibial insert conformity under knee flexion angle indicates highly regression suitable for the prediction. In addition, the FE simulation result was then verified by compared to mechanical testing using the Fujifilm technique. The result of FE analysis exhibited similar to that of the mechanical test. The study indicated that the different geometric designs of the insert conformity played a crucial role that influenced and relationship to the contact stress of TKA
Post-war Single-Family Houses in Europe under Pressure? A Demographic and Economic Framework for the Future Market of Elder Single-Family Housing Neighbourhoods
Authors: Berndgen-Kaiser Andrea , Fox-Kämper Runrid , Wiechert Markus
Published: April 2022

Recent research suggests that in some West German regions, single-family housing (SFH) neighbourhoods are prone to decay due to changed socio-economic and demographic trends. The question of whether similar demographic trends and implications for the SFH stock can be described for other West European countries such as Belgium, France, Netherlands and United Kingdom is the focus of the study. To explore that question, the research team compared figures (mainly Eurostat data) from these EU countries to data from Germany to highlight commonalities and country-specific differences. As the data analyses point out, except for Germany, the population in the four studied countries is growing slightly, but economic conditions are declining. A closer look at country-specific housing preferences shows very different percentages of detached and semi-detached houses in the entire housing stock as well as very different percentages of home ownership. In the studied countries, an emerging mismatch between supply and demand in older single-family housing estates is not currently observable, but demographic and economic factors foretell a growing mismatch, especially for the next decades. Municipalities should observe the future development of older single-family housing neighbourhoods and consider preventive measures at an early stage to avoid undesirable developments.
Governance of urban nature
Authors: Blanc Nathalie , Glatron Sandrine , Lamarche Thomas , Rankovic Aleksandar , Sourdril Anne
Published: April 2022

This paper analyses changes in the governance of urban nature in French urban policies over the past two decades. It demonstrates that the importance of “sustainable development” procedural principles has significantly declined in public policy agendas, a decline that has occurred alongside the rise to prominence of sectoral approaches based on performance and control, whether they focus on climate or urban biodiversity policies. Faced with these transformations in public action—namely the emergence of a centralized and sectoral management of urban policies ill-suited to the complex socio-environmental territories—collective movements in civil society are developing initiatives based on cooperation across territories. Consequently, the urban governance of nature reflects the conflicts between centralized policies and the composite and fragmented reality of the governance of nature in the city. We use the notion of “tinkering”, which refer to the general fragmentation of initiatives, actors, alliances and conflicts in the context of space usage in the field of urban nature, to describe these dynamics. Based on two studies of the urban policies developed by central French government authorities since the 1990s, we identify three principal discrepancies, based on three main separations, that illustrate “tinkering” with the governance of urban nature. The first relates to the discrepancy between “living nature” (biodiversity policies) and “physical-chemical nature” (in climate change policies) (Climate and biodiversity policies: sector-based governance). The second reflects the discrepancy between a technically oriented understanding of the environment and the sensory understanding of inhabitants (Discrepancies between representations and practices). Finally, the third concerns the different levels of action (Discrepancies in scale: the relationship between top-down and bottom-up governance).

Published: April 2022

Movies have become a significant part of today's generation. In this chapter, the authors worked on data mining and ML techniques like random forest regression, decision tree regression, support vector regression, and predict the success of the movies on the basis of ratings from IMDb and data retrieved from comments on social media platforms. Based on ML techniques, the chapter develops a model that will predict movie success before the release of the movie and thereby decrease the risk. Twitter sentimental analysis is used to retrieve data from Twitter, and polarity and subjectivity of the movie is calculated based on the user reviews, and those retrieved data machine learning algorithms are used to predict the IMDb rating. A predictive model is developed by using three algorithms, decision tree regression, SVR, and random forest regression. The chapter compared the results using three different techniques to get the movie success prediction at a reasonable accuracy.

The world has been put to a standstill by the COVID-19 pandemic, which has been caused by the SARS-CoV-2 (initially called 2019-nCoV) infecting agent. Moreover, this pandemic is spreading like a wildfire. Even the developed nations are running short of hospital beds and ventilators to treat the critically ill. Considering the total population of the world and the pace at which this pandemic is spreading, it not possible to hospitalize all the positive patients with intensive care facilities. In the chapter, the authors present a machine learning-based approach that will categorize the COVID-19 positive patients into five different categories, namely asymptomatic, mild, moderate, severe, and critical. The proposed system is capable of classifying the COVID-19-affected patients into five distinct categories using selected features of age, gender, ALT, hemoglobin, WBC, heart disease, hypertension, fever, muscle ache, shortness of breath with 97.5% accuracy.

Published: April 2022

Web recommendation is the process of providing personalization recommendations to the requirements of specific users. A lot of research is conducted on recommender systems by a broad range of communities including computer scientists and interdisciplinary researchers. In response, a lot of recommender systems have been developed so far. However, the complexity of these systems can lead to information overload and decreased utility for the users. For these reasons, researchers have sought to apply the techniques of recommender systems to deliver personalized views of social annotation systems. In this chapter, the authors cover recent improvements in recommender systems and explore the major challenges. This chapter finally presents a prototype for adaptation to end-users. The model emphasizes an annotation-based recommendation system for generating recommendations.
Effect of Vibrations on the Weld-Line Strength of Injection Molded Products
Authors: Minh Pham Son , Duong Thi Van Anh
Published: April 2022

In this research, vibrations were added to the mold structure. In the molding process, each vibration was turned on during the filling process. Moreover, the mold structure was re-designed to insert the vibration equipment. The design of this equipment is an early version used to insert vibrations. This option was chosen to facilitate the process of manufacturing and installing the vibration part. However, the applied method still has some limitations, such as not exerting an impact on the exact position where the weld line occurs. To overcome this disadvantage and to help increase the vibrations of the insert, we used a flexure hinge placed inside the insert. This design helped to improve the flow disturbance and to accurately impact the position where the weld line occurred. Therefore, the results of our method are better than those of the method currently being applied.
Correlating the Annealing Temperature Dependence of the Structural Inhomogeneity and the Diffusion in Zr-Ti-Cu-Ni-Be Glassy System
Authors: Aniya Masaru
Published: April 2022

The relation between the annealing temperature dependence of the structural inhomogeneity and the diffusion coefficient in a metallic glass forming system Zr-Ti-Cu-Ni-Be is studied by using reported experimental data. It is shown that the diffusion coefficient increases with the increase of the correlation length of the structural inhomogeneity. Interestingly, the result found resembles the behavior known in superionic glasses. A discussion on the found relationship is given by exploiting the model for the superionic glasses proposed by the author. Based on the model, an inhomogeneity dependent diffusivity maximum is predicted.

Published: April 2022

The incidence of right-sided infective endocarditis (RSIE) is steadily increasing and it has been reported to be associated with high risk of embolic events (EE). Aim of our study was to identify the clinical characteristics of patients with RSIE complicated by PE. Indeed, the identification of patients at high risk of significant PE who will benefit from a more aggressive therapeutic strategy may improve the prognosis. From January 2015 to September 2020, 176 patients (Pts) in 6 centers were found to have definite RSIE complicated by PE. Advanced imaging for PE including computed tomography pulmonary angiography (CTPA) was performed in 28 pts (16%) who represent our study group (24 male, mean age 50.6 ±18.29 years). They all underwent transesophageal echocardiography (TEE), in 12 cases (43%) also three-dimensional (3D) TEE, and 27 patients (99%) had both TEE and transthoracic echocardiography (TTE). A total of 53 vegetations (V) were detected. In 18 pts (64%) two or more vegetations were found. Native tricuspid valve was the most frequently involved valve (38 V, 71.7%), followed by catheter (5 V, 9.4%), tricuspid valve prosthesis (4 V, 7.5%), chordae and papillary muscle (2 V, 3.8%) and one vegetation (9%) in each of the following: pulmonic valve, inferior vena cava, eustachian valve, and right atrium. The most common location for vegetations was the anterior leaflet of the tricuspid valve (19 V, 35.8 %) followed by the posterior leaflet (11 V, 20.8%). The most common vegetations morphology was raceme-like shaped (35.8%). Staphylococcus aureus (S. aureus) was the most common causative pathogen (14 pts, 50%). The incidence of PE was very high in patients with vegetation length above 1.5 cm (median 17.6±6.5 mm by TEE). Our results suggest that a routine CTPA should be advised in the presence of vegetations larger than 1.5 cm and with S. aureus infection. This behavior would identify patients at high risk of PE who will benefit from a more aggressive therapeutic strategy, leading to an improvement in the prognosis. Further prospective studies are required to better confirm our hypothesis.

Published: April 2022

Background and purpose:

Ovarian cancer is one of the leading causes of cancer mortality in women. Despite the increase in cases of this cancer, the current therapeutic strategy is not effective. This study aimed to investigate the effect of cisplatin (Cis) with alantolactone (ALT) and ZnO nanoparticles (ZnONPs) in inducing apoptosis in SKOV3 ovarian cancer cells line.

Experimental approach:

To evaluate the viability of SKOV3 cells and determine the IC50 of Cis, ALT, and ZnONPs, MTT assay was used. Real-time PCR and western blotting were used to evaluate the expression levels of genes (XIAP, cyclin D1, Bcl-2, Bax, and MDM2) and proteins (XIAP, cyclin D1, Bcl-2, Bax), respectively. Also, cellular ROS levels were assessed by fluorimetry.

Findings / Results:

Our results showed that ALT and ZnONPs significantly increased the response to Cis in SKOV3 cells compared to the control and this response is remarkably increased in the triple combination (ALT-Cis-ZnONPs). The expression of XIAP, cyclin D1, and Bcl-2 genes and proteins in the groups treated with ALT, Cis, and ZnONPs as a single agent, double and triple combination were significantly reduced compared to the control, while Bax was generally shown an increase. Also, the level of intracellular ROS is higher in the treatment groups than in the control group and the highest increase was observed in the triple combination.

Conclusion and implications:

Taken together, our data demonstrated the potential therapeutic approach of using ALT and ZnONPs that may enhance the apoptotic effects of Cis on the SKOV3 cells.

We report the management of a case of inadvertent full-thickness scleral penetration during rhegmatogenous retinal detachment (RRD) surgery in a 14-year-old high myope while making partial-thickness scleral tunnel for the passage of the 240 silicone band. Sudden and gross hypotony with subretinal hemorrhage were noted post-penetration. Hypotony was immediately addressed by suturing the penetration site with a 7-0 vicryl suture. Subretinal blood was removed by performing 360° relaxing retinotomy and retinectomy and the retina was attached. This case report highlights the possible reasons for the full-thickness scleral penetration and one of the various methods to handle the same.

Published: April 2022

Fundus autofluorescence (FAF) is a noninvasive imaging tool helpful in various retinal and choroidal diseases. In this series, we report the utility of FAF in two cases of retinal artery occlusion (RAO). Cholesterol embolus was seen as a bright hyper autofluorescent foci on FAF in a case of branch RAO. Platelet fibrin embolus exhibited minimal hyper autofluorescence in another case of multiple RAO in contrast to bright hyper autofluorescence of cholesterol embolus. Fundus autofluorescence may be helpful in easier identification of cholesterol embolus in RAO and helps in differentiating it from platelet fibrin embolus.

Published: April 2022

A retinal infectious pathology, an acquired vertical nystagmus, and a suspicious neuroimaging result! Independently, these three entities are not uncommon. However, when they are consecutively observed in a young patient, it ramifies into an intriguing clinical scenario. A 17-year-old diagnosed case of diffuse unilateral subacute neuroretinitis presented to us with acute-onset vertical oscillations. On neuroimaging, she was found to have cerebellar dysgenesis. This case prompted us to revisit the pathogenesis of acquired vertical nystagmus and evaluate whether it resulted from disturbance of afferent (severe visual impairment) or efferent (cerebellar dysfunction) components of the neural integrator mechanism.

Very small number of minor salivary glands is seen around the larynx and trachea. A tumor originating from the salivary glands is infrequently seen in the respiratory tract. Pleomorphic adenoma (PA) is a benign tumor that can be seen on the head and neck area, most frequently involving major salivary glands. PA originating from the tracheobronchial tree is very rare. We describe here one of such cases, detected during the workup of a health-care worker that became infected with coronavirus disease 2019. Clinicians should be aware of benign tumors arising from the tissues of the central airways and avoid late diagnosis.

Authors: Agarwal Neelima , Gupta Manisha , Agrawal Alpana
Published: April 2022

Background:

Due to its physiologic immune suppression, pregnancy is a vulnerable time for severe respiratory infections including COVID-19. However, information regarding the effect of COVID-19 during pregnancy is limited.

Objectives:

To study the clinical profile of patients suffering from coronavirus disease-2019 (COVID-19) during pregnancy and to evaluate the effect of COVID-19 on maternal, perinatal, and neonatal outcomes.

Methodology:

This is a cross-sectional observational study over a period of one year from June 2020 to May 2021, in Level-3 Covid facility in Ghaziabad. All pregnant females with confirmed positive for Corona virus infection admitted to the covid ward under the department of Obstetrics & Gynecology were included in the study.

Results:

A total of 233 pregnant women were included in the study. Maximum patients were from age group 21-30 years (53.2), multigravida (62.7%), and presented in the third trimester (80.7%). On admission, 198 patients (85%) had no covid related symptoms and only three patients had severe symptoms requiring ICU care. Total 102 patients delivered (43.77%), out of whom 40 had a normal vaginal delivery and 62 had a cesarean section. The incidence of preterm birth was 22.5% and maternal death was in three patients (1.3%).

Conclusion:

The common presentation of COVID-19 during pregnancy is either a mild disease or even asymptomatic. The maternal outcomes observed in late pregnancy and fetal and neonatal outcomes appear good in most cases. Further studies are required to know long-term outcomes and potential intrauterine vertical transmission.

Authors: Malick Tanvi , Gupta Aarzoo , Arun Priti
Published: April 2022

ABSTRACT

Background:

The social demands and pressure often lead individuals of the sexual minority to enter heterosexual marriages resulting in the termination of ongoing same-sex relationships. Consequently, short-lived relations and multiple romantic or sexual partners.

Methods and Material:

The study aimed to assess couple satisfaction in relation to sexual satisfaction, mental health, and stigma in gay individuals. It was a correlational cross-sectional study conducted online through social media platforms using Google Forms. The assessment measures used were: Couple Satisfaction Index, New Sexual Satisfaction Scale, General Health Questionnaire, and Self-Stigma Scale. Out of a total of 115 posts, 92 responses were received from which a sample of 30 was analyzed using Statistical Package for the Social Sciences version 28. Descriptive statistics, Spearman’s correlation, and regression were computed to determine predictors of relationship satisfaction.

Results:

The correlation between sexual satisfaction and couple satisfaction (r = 0.52, P ≤0.01) was significant indicating that sexual satisfaction increases couple satisfaction. Psychological distress and stigma were inversely related to couple satisfaction but not to sexual satisfaction.

Conclusions:

Sexual satisfaction largely determined the couple’s satisfaction while psychological distress or stigma accounts for a small percentage of couple satisfaction.

ABSTRACT

Amyand’s hernia is a rare presentation accounting for about 1% of all inguinal hernias. It is usually a per-operative diagnosis, but may be picked up on preoperative ultrasound. Although rare, it is usually right-sided. We present here 3 cases of Amyand’s hernia, out of which one was on left side.
Notes on Maskit’s Planarity Theorem
Authors: Bowditch Brian H.
Published: April 2022

We give an account of the Planarity Theorem of Maskit. This gives a classification of finitely generated groups acting effectively properly discontinuously by orientation-preserving homeomorphisms on a planar surface. One can also realise such groups as Kleinian function groups. We also explain how one can give another proof of the planarity theorem using Dunwoody’s theory of tracks.

Published: April 2022

Background

Our research team developed a mobile application (app) to facilitate health-related self-management behaviors for secondary conditions among individuals with spinal cord injury (SCI). To facilitate mobile app adoption and ongoing use into the community, it is important to understand potential users’ expectations and needs.

Objectives

The primary objective of this study was to explore user expectations of a mobile app intervention designed to facilitate self-management behavior among individuals with SCI.

Methods

Data were collected via one-on-one, semi-structured interviews with a subsample of 20 community-dwelling participants enrolled in a larger, clinical trial. Analysis of the transcripts was undertaken using a six-phase process of thematic analysis.

Results

Our analysis identified three main themes for expectations of the mobile app intervention. The first theme, desiring better health outcomes, identified participants’ expectation of being able to improve their psychological, behavioral, and physical health outcomes and reduce associated secondary conditions. The second theme, wanting to learn about the mobile app’s potential, identified participants’ interest in exploring the functionality of the app and its ability to promote new experiences in health management. The third theme, desiring greater personal autonomy and social participation, identified participants’ desire to improve their understanding of their health and the expectation for the app to facilitate social engagement with others in the community.

Conclusion

By exploring end-users’ expectations, these findings may have short-term effects on improving continued mobile health app use among SCI populations and long-term effects on informing future development of mobile app interventions among chronic disease populations.
Evidence-Based Best Practice Toolkit for Competency-Based Orientation in Integrating an Adult Pneumococcal Protocol to Improve Vaccine Rate: A Program Evaluation Review
Authors:   ,   https://soar.usa.edu/cgi/viewcontent.cgi?article=1085&context=scholprojects, Angel Cifuentes Magda
Published: April 2022

Practice Problem: Low pneumococcal vaccine uptake among high-risk adults is partly due to underutilized or lack of nurse-driven vaccine protocols, limited understanding of vaccine intervals and indications by nurses, and lack of proper training. Currently, physician-driven orders are the only avenue for high-risk adults to obtain this vaccine in ambulatory sites. PICOT: In adults 65 years or older within an ambulatory setting, does the use of an adult pneumococcal vaccine protocol, compared to a physician order (no vaccine protocol) impact the rate of vaccination over 2 months? Evidence: Utilization of two or more interventions provided higher immunization rates. Interventions with stronger evidence rate include nurse-driven vaccine protocols, vaccine reminders, and use of electronic health system alerts. Review of programs and toolkits proved efficient interventions of vaccine programs based on CDC program evaluation framework. Intervention: The program evaluation yielded best practices for adult pneumococcal vaccine compliance utilizing nurse-driven protocols based on CDC recommendations and a competency-based orientation toolkit to support staff members when working in ambulatory settings. Outcome: A CBO toolkit was created to facilitate the ordering and administration of pneumococcal vaccines based on approved protocol to increase vaccine uptake. CBO toolkits offer nurses autonomy and increased competency with safe injection practices. Conclusion: Adult vaccine programs with nurse-driven protocols in combination with other modalities, prove effective to increase pneumococcal vaccine rates among high-risk groups and expands access to preventive health services provided by nursing staff. A CBO toolkit increases competency of injection practices of nurses in ambulatory settings.

Authors: ELMAOĞLU Erhan , ÖZDEMİR Serap
Published: April 2022

Giriş: Hemşirelikte karşılanamayan bakım son yıllarda dikkat çeken güncel bir konu olarak karşımıza çıkmaktadır. Amaç: Bu araştırmanın amacı pediatri hemşireleri tarafından karşılanamayan bakım ve nedenlerini belirlemektir. Yöntem: Tanımlayıcı kesitsel nitelikte olan araştırma 1-30 Haziran 2021 tarihleri arasında Gaziantep ilinde bir Kadın Doğum ve Çocuk Hastalıkları Hastanesi’nde yürütüldü. Araştırmanın evreni 500 pediatri hemşiresi oluşturdu. Araştırmanın örneklem sayısını belirlemek amacıyla G*Power (v3.1.9.7) programı kullanıldı ve toplam 403 hemşire örneklemi oluşturdu. Araştırmada; pediatri hemşirelerinin sosyo-demografik özellikleri ve mesleki özelliklere ilişkin bir soru formu ile “Pediatri Hemşireliğinde Karşılanamayan Bakım ve Nedenleri-Pediatrik Versiyon Anketi” kullanıldı. Bulgular: Araştırmada pediatri hemşirelerinin çalıştıkları son vardiyada %29 ile %87.3 oranında karşılanamayan hemşirelik bakımı olduğu belirlendi. Karşılanamayan bakımların sırasıyla; en çok hemşirelik bakım planına uyarak çocuğu kaldırma ve yürütme, ebeveynleri çocuğun bakımına dahil etme ve refakatçi tarafından yapılan uygulamaların değerlendirilmesi iken, en az sırayla günlük yatak başı vizite katılma, uygulanan ilaç etkinliklerinin değerlendirilmesi ve farmakolojik veya non-farmakolojik ağrı değerlendirmesi ile tüm hemşirelik verilerinin kayıt altına alınması olduğu saptandı. Hemşirelik mesleğini isteyerek seçmeyen, pediatri alanında çalışma yılı 1-5 olan ve bu alanda çalışmaktan kısmen memnun olan hemşirelerin; materyal, çalışan kaynaklı ve iletişim nedeni ile bakımı karşılayamadıkları ve aradaki farkların istatistiksel olarak anlamlı düzeyde olduğu saptandı (p ˂ .05). Sonuç ve Öneriler: Bu sonuçlara göre; pediatri hemşirelerinin son vardiyalarında en az bir bakımı karşılayamadığı, bakımı karşılayamama nedenlerinin en çok mesleki özellikleri ve deneyimlerden etkilendiği saptandı. Karşılanamayan bakımın nedenleri ve etkileyen faktörlerin belirlenmesi, hemşirelerin hizmet içi eğitimler ile desteklemesi ve kurumlarda bakım uygulamalarını güçlendirici politikaların benimsetilmesi önerilmektedir.
