Published: February 2024

To address instructional challenges and poor academic outcomes of youth in juvenile correctional facilities (JCFs), we must understand how and why some teachers are effective and why students are responsive to instruction in these settings. We observed and coded teacher–student instructional interactions from 733 fifteen-minute classroom reading sessions for seven teachers and 40 students in a secure U.S. JCF school. We then applied a series of time-window sequential analytic procedures to assess connections between instructional approaches and teacher behaviors, and contingent student engagement and response behaviors. We also compared contingent probabilities for students with disabilities and students without disabilities. Across all students, our observations were characterized by larger proportions of passive student engagement. We also found a relatively low use of teacher praise. When teachers provided either directives or opportunities to respond, conditional probabilities for appropriate student responses were higher across students, particularly when directives were provided to students with disabilities. We discuss additional results and implications for research and practice.

Published: February 2024

Purpose

To report a case of pitchfork sign following pars plana vitrectomy for idiopathic epiretinal membrane.

Study design

Case report.

Results

A 75-year-old man was referred to the surgical retina service due to a quantitative and qualitative decline in vision in the left eye (LE) for several months. Optical coherence tomography (OCT) examination revealed the presence of a stage III epiretinal membrane (ERM) according to the Govetto classification. Seven days after undergoing a 25-gauge pars plana vitrectomy (PPV) with ERM peeling and balanced salt solution (BSS) tamponade, OCT examination revealed the presence of the ‘pitchfork sign’ in the macular region, along with the detection of a choroidal neovascularization (CNV) through OCT-A examination. After receiving two monthly intravitreal anti-VEGF injections, a complete regression of the MNV was observed.

Conclusions

We reported, for the first time, the iatrogenic onset of the pitchfork sign following vitreoretinal surgery. This discovery highlights the unique presentation of the pitchfork sign in the context of surgical procedures, expanding our comprehension of its range of causes.
A comparison of microstructure and mechanical characteristics correlation of the joint specimens for duplex stainless steel UNS S32304 and super-duplex stainless steel UNS S32750: The role of post-weld heat treatment

Published: February 2024

The present investigation studies the impact of post-weld heat treatment (PWHT) on the microstructure and mechanical characteristics of joints made by gas tungsten arc welding between duplex stainless steel and super-duplex stainless steel specimens. The PWHT process was considered at 1100 °C for 10 minutes followed by water quenching on UNS S32304 and UNS S32750 materials. Scanning electron microscopy, optical microscopy, X-ray diffractometry (XRD), and energy dispersive X-ray analyses have been applied in microstructure evolution, including recognizing local chemical contents and elemental distribution. To analyze the mechanical characteristics of samples, tensile and hardness tests were performed. It was shown that after applying PWHT, the morphology of the austenite varied becoming mostly intergranular/spheroidal in shape, accompanied by an improvement in the percentages of austenite. This investigation indicates the PWHT results in restoring an equal percentage of both phases. The phase percentages, based on both ASTM E1245 and ASTM E562, show a good agreement between the austenite and ferrite phases of weld materials. According to XRD, the phases are mainly ferrite and austenite with different lattice parameters with no evidence of unwanted intermetallic phases. It was concluded that the PWHT process plays a crucial role in the ductility of joint specimens due to the phase balance between austenite and ferrite.

Authors: Abou Said Sara , Abdallah Wael
Published: February 2024

This study examines lifelong learning as it pertains specifically to professional growth for university educators in Kuwait. Moreover, it looks at how self-directed and lifelong learning are interrelated. The findings of this study indicate a significant direct relationship between lifelong learning factors, including motives, attitudes, and conditions, and the professional development of educators, except for the attitude with the reflection activities. The current study employs a deductive and quantitative research approach through a questionnaire survey. Partial least square-structural equation modelling (PLS-SEM) was used to analyze the data. The findings underscore the effectiveness of self-directed lifelong learning in meeting educators’ professional development needs and improving their practice. Educational institutions should prioritize and support lifelong learning initiatives to foster educators' growth and enhance teaching and learning in post-compulsory education settings.

Authors: Zhu Zheng , Wu Yaohua , Qu Ling , Zou Ying , Nie Guozhong , Xu Shuguang , Zhou Qixing , Zhang Yunfeng , Chen Rui
Published: February 2024

Objective

The aim of this study is to investigate how much intermittent hypoxemia and airflow limitation contribute to cognitive impairment in overlap syndrome (OS), which is the coexistence of two common diseases, obstructive sleep apnea hypopnea syndrome (OSAHS) and chronic obstructive pulmonary disease (COPD).

Methods

We conducted a cross-sectional study of patients with OSAHS, COPD or OS, compared with normal controls, to determine the association between sleep apnea/pulmonary function-related indicators and cognitive dysfunction in individuals with OSAHS, COPD or OS.

Results

A total of 157 participants were recruited. Both OSAHS and OS presented lower adjusted Montreal cognitive assessment (MoCA) scores compared with COPD group. In addition, the MoCA score was significantly lower in COPD group compared with control group. The incidence of cognitive impairment was 57.4% in OSAHS group, and 78% in OS group, which were significantly higher than COPD group (29%) and control group (8.8%). Furthermore, a broader range of cognitive domains were affected in OS group compared with OSAHS group. Elevated levels of oxygen desaturation index (ODI) and/or apnea hypopnea index (AHI) were positively correlated with increased Epworth sleeping scale (ESS) in OSAHS and OS. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and peak expiratory flow (PEF) were positively correlated with cognitive scores in OSAHS but not in OS. Serum level of hypoxia-inducible factor-1α (HIF-1α) was significantly higher in OS. Logistic regression identified ODI as an independent risk factor for cognitive impairment in OS, while severity of snoring and PEF were independent risk factors in OSAHS.

Discussion

This study revealed significant cognitive impairment in OS, OSAHS and COPD. Sleep-related indicators are warranted in OS patients for detection, differentiation and grading of cognitive impairment, whereas pulmonary functions are warranted in OSAHS patients for detection and early intervention of cognitive impairment.

Published: February 2024

Introduction:

The aim of this study is to present single-center outcomes in patients treated with in situ laser fenestration thoracic endovascular aortic repair (LFTEVAR) for various aortic arch pathologies and assess the impact of increasing experience.

Methods:

The STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement was followed. A retrospective analysis of prospectively collected single aortic center data was conducted, including baseline information and peri- and post-operative outcomes of consecutive patients managed with LFTEVAR for aortic arch pathologies. Patients were enrolled from April 1, 2017 to January 31, 2023. The cohort was dichotomized to compare early (2017-2019) and late experience (2020-2023). Primary outcomes were peri-operative mortality and cerebrovascular morbidity.

Results:

Thirty patients were included (63.3% males, mean age 69.8±9.6 years); 21.4% presented with aortic ruptures. Aortic aneurysm involving the aortic arch was the most frequent pathology (53.3%). Forty target vessels (TVs) were revascularized, including 19 left subclavian arteries (47.5%) and 17 left common carotid arteries (42.5%). Double fenestrations were performed in 10 patients. The proximal landing zone was Ishimaru zone 0 in 5 patients (16.7%) and zone 1 in 13 patients (43.3%). Technical success was 93%. No spinal cord ischemia was recorded, and 3 patients (10%) suffered a post-operative stroke, of which 1 was major (3.3%). The median follow-up was 12 months (range=1-48 months). Thirty-day and follow-up mortality rates were 13.5% and 15.3%, respectively. Target vessel instability was 10%, of which 3.8% required reintervention. There was no statistically significant difference in outcomes between the early and late experience groups.

Conclusions:

Laser fenestration thoracic endovascular aortic repair of the aortic arch performed in experienced aortic centers is associated with low early mortality and stroke rates. It is a safe and effective therapeutic option in patients considered unfit for open repair.

Clinical Impact

Custom-made devices for arch pathologies requiring urgent repair are not an option because of manufacturing delays. Off-the-shelf devices with single branch arch prostheses, and outside IFU techniques such as parallel-grafts and surgeon-modified endografts have been proposed in this setting. Another off-the-shelf alternative is in situ laser fenestration thoracic endovascular repair (LFTEVAR), which addresses many limitations of the other off-the-shelf options. Our study reports the outcomes of 30 patients treated with LFTEVAR, showing that it is a viable therapeutic option in patients considered unfit for open repair acknowledging that sufficient experience with complex endovascular aortic repair is mandatory to achieve acceptable outcomes in these high-risk patients with challenging aortic anatomies.
Public involvement in Australian clinical trials: A systematic review
Authors: Zirnsak Tessa-May , Ng Ashley H , Brasier Catherine , Gray Richard
Published: February 2024

Background

Public involvement enhances the relevance, quality, and impact of research. There is some evidence that public involvement in Australian research lags other countries, such as the United Kingdom. The purpose of the systematic review was to establish the rates and describe the characteristics of public involvement in Australian clinical trials.

Methods

We reviewed evidence of public involvement in all Australian randomised controlled trials published in the first 6 months of 2021. To determine the quality of public involvement, we used the five-item short-form version of the Guidance of Reporting Involvement Patients and the Public, version 2.

Results

In total, 325 randomised controlled trials were included, of which 17 (5%) reported any public involvement. Six trials reported public involvement in setting the research aim and seven in developing study methods. The authors of one study reflected on the overall role and influence of public involvement in the research.

Conclusion

Rate of public involvement in Australian clinical trials is seemingly substantially lower than those reported in countries with similar advanced public health care systems, notably the United Kingdom. Our observations may be explained by a lack of researcher skills in how to involve the public and the failure by major funding agencies in Australia to mandate public involvement when deciding on how to award grant funding.
Practices and perceptions of strength and conditioning in female golf: A survey study of touring professionals
Authors: Robinson Luke , Murray Andrew , Mountjoy Margo , Scott Fiona , Glover Danny , Coughlan Daniel , Turner Anthony , Bishop Chris
Published: February 2024

The aim of the study was to provide an understanding of current practices and perceptions of strength and conditioning (S&C) training in female touring professionals. A cross-sectional, explorative survey was undertaken and contained 30 questions separated into four sections: (i) general participant information, (ii) S&C practices, (iii) Likert scale questions on S&C for golf performance, and (iv) knowledge and awareness of S&C. A total of 102 players completed the survey with a combination of multiple-choice questions (MCQs), open-ended questions, and Likert scale style questions utilised throughout. Results showed that ≥94% of players believed that strength and power in both the lower and upper body, in addition to flexibility, were the most important physical characteristics to complement golf shot metrics (e.g. clubhead speed [CHS], ball speed, carry distance, etc.). However, 26% of players conducted S&C training only in the off-season, with 21% suggesting that they had a fear of injury from S&C training. When considering the barriers to undertaking S&C training, the most common reasons included time constraints (20%) and players wanting to prioritise golf practice (15%). Finally, 58% of players believed that training in the weight room should replicate the golf swing. Although it is positive to see that the main physical characteristics for golf are well-understood by professional players, it is also evident that further education and knowledge translation is required relating to the application of S&C training for performance enhancement and injury risk mitigation purposes.
Exploring the Philippines’ Evolving Grand Strategy in the Face of China's Maritime Expansion: From the Aquino Administration to the Marcos Administration
Authors: De Castro Renato Cruz
Published: February 2024

This article explores the Philippines’ evolving and changing grand strategies in confronting China's maritime expansion in the South China Sea. From 2010 to 2016, under the Aquino administration, the Philippines challenged China's extensive claim over the disputed waters by adopting a hard-balancing approach. In 2016, the succeeding Duterte administration pursued an appeasement policy; in 2018, it shifted to a limited hard balancing policy because of (a) continuing Chinese coercive actions against Armed Forces of the Philippines units in Philippines-occupied land features in the South China Sea and (b) China's failure to deliver on its promised public investments in the country's infrastructure building programme. President Ferdinand Marcos Jr initially adhered to his predecessor's strategy of limited hard-balancing. Seeing no change in China's stance on the maritime issue, he resorted to a hard-balancing policy. He has vigorously supported the steady modernisation of the Philippine military and strengthened the country's defence ties with the United States and other like-minded security partners while maintaining cordial diplomatic and economic relations with China. This article argues that the Philippines’ evolving grand strategy has the following elements: (a) Admitting that China's maritime expansion is the quintessential threat to Philippine national security; (b) pursuing a policy of maintaining the status quo in the West Philippine Sea/South China Sea; (c) acknowledging the urgency to shift the focus of the Philippine military from internal security to territorial defence; and (d) fostering its alliance with the United States and its security partnerships with other American allies and partners.

In the contemporary landscape of construction project management, the strategic integration of Building Information Modeling (BIM) methodology has emerged as a fundamental avenue to improve operational efficiency. This study evaluates the feasibility and effectiveness of the implementation of the BIM methodology in improving the management of construction projects in construction companies in Peru. Using an applied approach underscored by a quantitative and correlational non-experimental design, a comprehensive survey was administered to 415 workers. This survey focused on evaluating the dimensions of BIM (3D, 4D, and 5D), as well as the fundamental facets of project management that encompass planning and execution. The results reveal that 47% of respondents highlighted deficiencies within the 3D BIM dimension, indicating potential challenges in visualizing and understanding the design. Likewise, 49% of participants highlighted deficiencies within the 4D BIM dimension, shedding light on issues related to time coordination and strategic planning. Around 57% expressed reservations about the 5D BIM dimension, highlighting the complexities surrounding accurate cost estimation and financial management. The synthesis of these revelations underscores an urgent call for specific interventions to rectify these specific areas. This involves investing in cutting-edge BIM technology tools and the simultaneous provision of targeted training programs for stakeholders to increase their multi-dimensional view of BIM. Ultimately, the study results drive innovation, thus opening the prospect of a more sustainable and streamlined construction industry.

Authors: Balić-Žunić Tonči , Nestola Fabrizio , Pamato Martha G. , Rasmussen Maja B.
Published: February 2024

Kristjánite, KNa2H(SO4)2, is a new mineral (IMA2022–131) found in a high-temperature fumarole on Fimmvörðuháls, Iceland. It is monoclinic, P21/n, a = 6.9625(1), b = 9.9953(1), c = 11.0928(2) (Å), β = 105.637(2)° and V = 743.40(2) Å3. Kristjánite forms colourless transparent crystals up to ~100 μm in size in compact aggregates with metathénardite, belomarinaite, aphthitalite, ivsite and an unknown mineral with tentative composition K2NaH(SO4)2, or grows in white globules of smaller grains on their surface. The eight strongest maxima in a powder X-ray diffraction diagram are [d, Å (Intensity)] 4.37 (59), 3.65 (32), 3.48 (78), 3.36 (100), 3.18 (76), 2.83 (43), 2.73 (38) and 2.405 (23). The mineral represents a novel crystal structure type. In it, K is coordinated by eight O atoms, and two symmetrically independent Na atoms by seven O atoms. Two symmetrically independent S atoms are in tetrahedral coordination by O atoms. A close to linear, very short hydrogen bond (2.44 Å), connects the two to a SO4–H–SO4 dimer. K and Na coordination polyhedra share vertices, edges and even faces forming with sulfate tetrahedra a tight structure with narrow [100] channels lined on two opposite sides by hydrogen bonds.

Authors: Bolat Ibrahim , Korkmaz Kubra , Dogan Meral , Turan Metin , Kaya Cengiz , Seyed Hajizadeh Hanifeh , Kaya Ozkan
Published: February 2024

Background

Drought and heat stress are significant concerns to food security in arid and semi-arid regions, where global warming is predicted to increase both frequency and severity. To cope with these challenges, the use of drought-tolerant plants or technological interventions are essential. In this study, the effects of foliar potassium nitrate (KNO3) application on the stress tolerance and recovery of Myrobalan 29C rootstocks (Prunus cerasifera Ehrh.) were evaluated. These rootstocks are widely recognized for their adaptability and are extensively used in fruit production. To assess their response, the rootstocks were subjected to drought, heat shock, or a combination of both stressors. Additionally, they were treated with 1.0% KNO3 via foliar application. Throughout the stress and recovery periods, various morphological, physiological, and bio-chemical parameters were measured.

Results

Based on our results, KNO3 treatment improved LRWC, Chl stability, SC, and key stress markers like proline, MDA, H2O2, along with antioxidant enzymes CAT, SOD, POD during both stress and recovery phases. Moreover, our results emphasized KNO3's critical role in hormone regulation under stress. KNO3 application significantly altered hormone levels, notably increasing ABA during drought and heat shock stress, essential for stress response and adaptation. In contrast, IAA, GA, and cytokinin’s significantly increased during the recovery phase in KNO3-treated plants, indicating improved growth regulation and stress recovery. In addition, KNO3 application improved the recovery process of the rootstocks by restoring their physiological and biochemical functions.

Conclusion

This study suggests that the application of foliar KNO3 is an effective technique for enhancing the drought and heat tolerance as well as the recovery of Myrobalan 29C rootstocks. These results hold significant value for farmers, policymakers, and researchers, as they offer crucial insights into the development of drought-tolerant crops and the management of climate change’s adverse effects on agriculture.

Published: February 2024

Drought stress poses a significant challenge to maize production, leading to substantial harm to crop growth and yield due to the induction of oxidative stress. Deashed biochar (DAB) in combination with carboxymethyl cellulose (CMC) presents an effective approach for addressing this problem. DAB improves soil structure by increasing porosity and water retention and enhancing plant nutrient utilization efficiency. The CMC provides advantages to plants by enhancing soil water retention, improving soil structure, and increasing moisture availability to the plant roots. The present study was conducted to investigate the effects of DAB and CMC amendments on maize under field capacity (70 FC) and drought stress. Six different treatments were implemented in this study, namely 0 DAB + 0CMC, 25 CMC, 0.5 DAB, 0.5 DAB + 25 CMC, 1 DAB, and 1 DAB + 25 CMC, each with six replications, and they were arranged according to a completely randomized design. Results showed that 1 DAB + 25 CMC caused significant enhancement in maize shoot fresh weight (24.53%), shoot dry weight (38.47%), shoot length (32.23%), root fresh weight (19.03%), root dry weight (87.50%) and root length (69.80%) over control under drought stress. A substantial increase in maize chlorophyll a (40.26%), chlorophyll b (26.92%), total chlorophyll (30.56%), photosynthetic rate (21.35%), transpiration rate (32.61%), and stomatal conductance (91.57%) under drought stress showed the efficiency of 1 DAB + 25 CMC treatment compared to the control. The enhancement in N, P, and K concentrations in both the root and shoot validated the effectiveness of the performance of the 1 DAB + 25 CMC treatment when compared to the control group under drought stress. In conclusion, it is recommended that the application of 1 DAB + 25 CMC serves as a beneficial amendment for alleviating drought stress in maize.
Emergency department utilisation and treatment for trauma-related presentations of adolescents aged 16–18: a retrospective cross-sectional study
Authors: Brockhus Lara , Hofmann Elias , Keitel Kristina , Bärtsch Martina , Müller Martin , Klukowska-Rötzler Jolanta
Published: February 2024

Background

A recent study conducted at our tertiary hospital emergency department (ED) reviewed ED consultations and found that adolescents aged 16–18 years present significantly more often for trauma and psychiatric problems than adults over 18 years. Accidental injuries are one of the greatest health risks for children and adolescents. In view of the increased vulnerability of the adolescent population, this study aimed to further analyse trauma-related presentations in adolescents.

Methods

We conducted a single-centre, retrospective, cross-sectional study of all adolescent trauma patients aged 16 to 18 years presenting to the adult ED at the University Hospital (Inselspital) in Bern, Switzerland, from January 2013 to July 2017. We analysed presentation data as well as inpatient treatment and cost-related data. Data of female and male patients were compared by univariable analysis. A comparison group was formed consisting of 200 randomly chosen patients aged 19–25 years old with the same presentation characteristics. Predictive factors for surgical treatment were obtained by multivariable analysis.

Results

The study population included a total of 1,626 adolescent patients aged 16–18 years. The predominant causes for ED presentation were consistent within case and comparison groups for sex and age and were sports accidents, falls and violence. Male patients were more likely to need surgical treatment (OR 1.8 [95% CI: 1.2–2.5], p = 0.001) and consequently inpatient treatment (OR 1.5 [95% CI: 1.1–2.1], p = 0.01), associated with higher costs (median 792 Swiss francs [IQR: 491-1,598]). Other independent risk factors for surgical treatment were violence-related visits (OR 2.1 [95% CI: 1.3–3.5, p = 0.004]) and trauma to the upper extremities (OR 2.02 [95% CI: 1.5–2.8], p < 0.001). Night shift (OR 0.56 [95% CI: 0.37–0.86], 0.008) and walk-in consultations (OR 0.3 [95% CI: 0.2; 0.4, < 0.001] were preventive factors for surgical treatment.

Conclusions

Male adolescents account for the majority of emergency visits and appear to be at higher risk for accidents as well as for surgical treatment and/or inpatient admission due to sports accidents or injuries from violence. We suggest that further preventive measures and recommendations should be implemented and that these should focus on sport activities and injuries from violence.
The non-conveyance of trauma patients in Swedish emergency medical services: a retrospective observational study of the trauma population not transported to an emergency department
Authors: Larsson Glenn , Eldh Jana , Hagman Elisabeth , Andersson Hagiwara Magnus
Published: February 2024

Introduction

Due to a systemic modification in Swedish emergency medical services (EMS) staffing in recent years, the nature of the Swedish EMS has changed. Transport to an emergency department (ED) is no longer the only option. Referrals and non-conveyance form a growing part of EMS assignments. Trauma is one of the most common causes of death and accounts for 17% of Swedish EMS assignments. The aim of this study was to describe the characteristics and clinical outcomes of non-conveyed trauma patients who were assessed, treated and triaged by the EMS to gain a better understanding of, and to optimise, transport and treatment decisions.

Methods

The study had a descriptive, retrospective and epidemiologic design and was conducted by reviewing EMS and hospital records for 837 non-conveyed trauma patients in the southwest of Sweden in 2019.

Results

Three in four non-conveyed trauma patients did not seek further medical care within 72 h following EMS assessment. The patients who were admitted to hospital later were often older, had suffered a fall and had a medical history. Half of all the incidents occurred in a domestic environment, and head trauma was the major complaint. Less than 1% of the studied patients died.

Conclusion

Most of the non-conveyed trauma patients did not seek further medical care after being discharged at the scene. Falling was the most common trauma event, and for the older population, this meant a higher risk of hospital admission. The reasons for falls should therefore be investigated thoroughly prior to non-conveyance decisions. Future studies should focus on the reasons for non-conveyance and measure the morbidity and invalidity outcomes rather than mortality.
GADNN: a revolutionary hybrid deep learning neural network for age and sex determination utilizing cone beam computed tomography images of maxillary and frontal sinuses
Authors: Hamidi Omid , Afrasiabi Mahlagha , Namaki Marjan
Published: February 2024

Introduction

The determination of identity factors such as age and sex has gained significance in both criminal and civil cases. Paranasal sinuses like frontal and maxillary sinuses, are resistant to trauma and can aid profiling. We developed a deep learning (DL) model optimized by an evolutionary algorithm (genetic algorithm/GA) to determine sex and age using paranasal sinus parameters based on cone-beam computed tomography (CBCT).

Methods

Two hundred and forty CBCT images (including 129 females and 111 males, aged 18–52) were included in this study. CBCT images were captured using the Newtom3G device with specific exposure parameters. These images were then analyzed in ITK-SNAP 3.6.0 beta software to extract four paranasal sinus parameters: height, width, length, and volume for both the frontal and maxillary sinuses. A hybrid model, Genetic Algorithm-Deep Neural Network (GADNN), was proposed for feature selection and classification. Traditional statistical methods and machine learning models, including logistic regression (LR), random forest (RF), multilayer perceptron neural network (MLP), and deep learning (DL) were evaluated for their performance. The synthetic minority oversampling technique was used to deal with the unbalanced data.

Results

GADNN showed superior accuracy in both sex determination (accuracy of 86%) and age determination (accuracy of 68%), outperforming other models. Also, DL and RF were the second and third superior methods in sex determination (accuracy of 78% and 71% respectively) and age determination (accuracy of 92% and 57%).

Conclusions

The study introduces a novel approach combining DL and GA to enhance sex determination and age determination accuracy. The potential of DL in forensic dentistry is highlighted, demonstrating its efficiency in improving accuracy for sex determination and age determination. The study contributes to the burgeoning field of DL in dentistry and forensic sciences.

This study was to identify the type of perceptions on health conservation of elderly hemodialysis patients and compare the characteristics of perceptions.

Methods

This study used an exploratory study design applying Q methodology, which is designed to research subjectivity. The study determined a population of subjective statements, the concourse, based on the preceding literature and interviews with twenty-five elderly patients over 65 years of age with hemodialysis. We chose a total of 50 statements considered to be representative of the concourse for the Q-sample. The study selected 50 elderly patients over 65 years of age with hemodialysis as the P-set. The participants provided their internal viewpoints by sorting the Q-sample items into a grid. The researchers performed an analysis using PC-QUANL program. Data were collected from June to November, 2019.

Results

Type I, ‘support system-based effort’ focused on one’s own effort, positive and proactive attitude, family support, medical instructions, information, and medications. Type II, ‘skeptical life maintaining’ expressed a pessimistic future without hope, strongly negative perception on preserving health, and thus minimal effort and motivation to continue life. Type III, ‘treatment process interest’ is based on an interest in the hemodialysis process; for them, it is important to follow medical staff’s instructions, take regular medications precisely, pay attention to the results of regular monthly blood tests, and control their health. Type IV, ‘positive effort’ accepts hemodialysis positively, lives with hemodialysis, and carries out all daily life activities.

Conclusion

In nursing practice, nurses need to pay attention to the perceptions on health conservation of elderly hemodialysis patients. This study can be implied as the evidence of nursing practice based on the perception on health conservation of elderly hemodialysis patients.
Could driving help us to “see better”? A comparative assessment of saccadic efficiency, visual speed, and attention
Authors: Gené-Sampedro Andrés , Alonso Francisco , Gene-Morales Javier , Monteiro Pedro Lourenço , Useche Sergio A.
Published: February 2024

Background

This study aimed at comparing drivers’ and non-drivers’ results in the Adult Developmental Eye Movement with Distractors test (ADEMd) and the Useful Field of View test (UFOV).

Methods

One hundred and twenty Spaniards (mean age 50.90 ± 17.32 years) without eye disease voluntarily participated in this cross-sectional descriptive study. Participants in a single experimental session completed a questionnaire on sociodemographic, health, eyesight, and driving information. They also performed the ADEMd and UFOV tests randomly following standardized protocols. The ADEMd is a visual-verbal test that measures saccadic efficiency and visual attention. Brown-Forsythe (B–F) tests with Games-Howell post-hoc adjustments were conducted to assess differences between groups. Groups were formed according to sex, age (young adults, adults, and older adults), and driver/non-driver for further analysis. Additionally, associations between dependent variables were assessed through Spearman’s correlations.

Results

Drivers obtained significantly better results in the ADEMd compared with non-drivers. Non-significant differences between drivers and non-drivers were encountered in the UFOV. Additionally, significant differences were observed between sexes and age groups. It is worth highlighting that non-driver’s age significantly correlated with worse ADEMd performance (rho = .637 to .716). This correlation was non-significant in drivers. Similarly, reading hours significantly correlated with better ADEMd performance in non-drivers (rho = − .291 to − .363), but not in drivers. The only significant correlations between ADEMd and UFOV tests were found in drivers (rho = .307 to .410).

Conclusion

Considering all the discussed results, it could be hypothesized that the driving task promotes abilities, such as oculomotor and cognitive function, which are relevant for the performance in the ADEMd. However, this hypothesis is based on correlational outcomes and further studies should causally assess this possible relation.
Exploring the connection between ego-resiliency and health behaviors: a cross-sectional study of Polish health sciences students
Authors: Dębska-Janus Małgorzata , Dębski Paweł , Nawrocka Agnieszka , Polechoński Jacek , Madejczyk Wojciech , Badura-Brzoza Karina
Published: February 2024

Background

The aim of this study was to examine the relationship between ego-resiliency and the intensity of health behaviors among Polish health sciences students.

Methods

The study involved 483 students from health-related faculties in southern Poland, consisting of 314 women (63.7%) and 179 men (36.3%). The average age of the participants was 21.7 ± 2.5 years. To assess resiliency (ER), the Ego-Resiliency Scale (ER89-R12) by Block and Kremen was used in its Polish adaptation. The intensity of health behaviors was examined using the Health Behavior Inventory (HBI) developed by Z. Juczyński.

Results

The results revealed a positive correlation between the intensity of health behaviors and ER (r = 0.43, p < 0.001), both for the general factor and its categories (positive mental attitude, proper eating habits, preventive actions, and prohealth activities). Students with a high level of health behaviors exhibited significantly higher ER (M = 38.95, SD = 5.15) compared to those with average (M = 35.93, SD = 5.03) and low (M = 32.97, SD = 5.12) HBI levels. Among the HBI categories, Positive Mental Attitude showed the strongest correlation with both general ER and its factors: optimal regulation (OR) and openness to life experiences (OL). Furthermore, the correlation was found to be stronger with the OR and weaker with OL.

Conclusion

Higher ER in students is correlated with a greater frequency of health behaviors. Nurturing the development of ER may contribute to the maintenance of prohealth practices despite life difficulties and temporary loss of motivation. This, in turn, promotes the regularity of health behaviors, which is crucial for their positive impact on overall health.
Trends, patterns and predictors of high-risk fertility behaviour among Indian women: evidence from National Family Health Survey
Authors: Singh Pooja , Singh Kaushalendra Kumar
Published: February 2024

Background

Numerous studies have demonstrated that high-risk fertility behaviour (HRFB), which includes maternal age below 18 or above 34 years, short birth intervals (less than 24 months), and high parity (birth order above 4), is associated with adverse maternal and child health outcomes. There is a substantial research gap in the domain of high-risk fertility behaviour in the Indian context. Therefore, this study is designed to investigate the current trends and patterns in the prevalence of high-risk births among Indian women, with a primary focus on identifying contributing factors associated with this prevalence.

Methods

The study utilized data from the nationally representative National Family Health Survey (NFHS), which has been conducted in five rounds since 1992–93. Data from all rounds were used to assess the overall trend. However, data from the most recent round of NFHS, conducted during 2019–21, were employed to evaluate current levels and patterns of HRFB prevalence and to identify socio-economic and demographic predictors of HRFB using binomial and multinomial logistic regression models.

Results

The prevalence of HRFB has exhibited a consistent decreasing pattern from 1992 to 93 to 2019–21 in India. However, 29.56% of married women continue to experience high-risk births with notably higher rates in several states (e.g., 49.85% in Meghalaya and 46.41% in Bihar). Furthermore, socio-demographic factors like wealth index, educational level, social group, religion, mass media exposure, family size, age at marriage, type and region of residence, and reproductive factors like birth intention, place and type of delivery, ANC visits and current contraceptive use were identified as significant predictors of high-risk births among women in India.

Conclusion

Despite a 20.4 percentage point decline in HRFB prevalence over the past three decades, a significant proportion of women in specific regions and demographic subgroups continue to experience high-risk births. Therefore, the present study recommends interventions aimed at preventing high-risk births among women in India, with particular emphasis on states with high HRFB prevalence and women from socioeconomically disadvantaged backgrounds.
(Over)crowded house: exploring asylum seekers’ experiences of the COVID-19 pandemic while living at accommodation centers in Sweden
Authors: van Eggermont Arwidson Charlotta , Holmgren Jessica , Tinghög Petter , Eriksson Henrik , Gottberg Kristina
Published: February 2024

Background

The COVID-19 pandemic has made visible the scale of health disparities in society, highlighting how the distribution of infection and deaths differs between population subgroups within countries. Asylum seekers represent a potentially vulnerable group; early in the pandemic, concerns were raised about their housing situation, usually involving overcrowded, camp-like accommodations, and the effects of COVID-19 in relation to this. Hence, this study aimed to explore asylum seekers’ experiences of the COVID-19 pandemic while living at accommodation centers.

Methods

In this qualitative study, 14 semi-structured interviews were conducted with asylum seekers at two accommodation centers in Sweden. Participants represented a diverse group of asylum seekers in regard to age, educational background, and gender. Data were analyzed using qualitative content analysis.

Results

Experiences related to COVID-19 were highly dependent on the living situation at the accommodation centers and the experience of feeling unsafe in shared spaces. This was enhanced by the experiences of a challenging mix of COVID-19 messages where different understandings of COVID-19 and related measures existed, together with a feeling of loss of control and safety in shared rooms. Additionally, participants felt more isolated from the outside society and missed prior social activities. Adding to this experience of isolation was an increasing mistrust regarding the authorities’ pandemic response.

Conclusion

This study highlights the importance of understanding the specific challenges and vulnerabilities of asylum seekers at accommodation centers during the pandemic, shaped by their housing situation and legal status. The findings underscore the need for context-specific support, holistic disease prevention approaches, and tailored health communication strategies using diverse formats. Additionally, the findings emphasize the crucial need to identify and mobilize existing community resources in planning and implementing pandemic control measures. Furthermore, the study emphasizes governmental responsibility in providing secure housing, and to address long-term vulnerabilities beyond pandemics.
