The influence of teachers’ psychological capital on the quality of work life: exploring the mediating impact of emotions
Authors: Erden Hale 
Published: February 2025

IntroductionThe aim of this study is to investigate whether emotions play a mediating role in determining the effect of teachers’ psychological capital (PsyCap) on the quality of work life (QWL).MethodsThe current study presents an investigation on the mediating role of emotions and their effect on teachers’ PsyCap at their work life. The study used scales including Psychological Capital Scale (PsyCapS), Quality of Work Life Scale (QWLS) and Emotions Scale (ES). The scales were all applied to administrators and teachers in state schools in TRNC. The sample of the study consists of 369 teachers and school administrators. Data were analyzed using SPSS 27.0 for descriptive statistics and correlation analyses. In addition, structural equation modeling was performed with AMOS to examine the potential mediating effect of emotions on the relationship between PsyCap and QWL.ResultsAs a result, the mediating role of emotions in the relationship between teachers’ PsyCap and perceptions of QWL was fully supported. There was a significant correlation between teachers’ PsyCap, perceptions of QWL and emotions. PsyCap was found to have a significant and positive effect on both emotions and perceptions of QWL. In addition, PsyCap was found to have a significant positive relationship with QWL.DiscussionAmong TRNC teachers, PsyCap has a significant positive relationship with both emotions and perceptions of QWL. PsyCap can directly or indirectly increase the perception of QWL through the relationship with emotions. Therefore, teachers’ positive PsyCap can positively increase their emotions and perceptions of QWL.

IntroductionProblematic Social Media Use (PSMU) refers to an individual’s long-term, high-intensity use of social media. Although this behavior is not pathological, it has a negative impact on the physical and mental health of individuals. In the past, intervention methods used for PSMU often controlled behavior to reduce the usage time of individual social media platforms. However, because psychological needs satisfaction and unreasonable cognition that lead to the problematic use of social media by individuals are not considered, behavior-based treatment models often do not address this problem.Method30 participants with PSMU (with another 30 participants as a control group) participated in an intervention program of mindfulness-based cognitive therapy (MBCT) combined with metaphor therapy (MT).ResultsThe results showed that these therapies changed the participants’ cognition and behavior and achieved a good intervention effect.ConclusionThe MBCT combined with MT can be used as an intervention for patients with PSMU.

BackgroundAntimicrobial resistance (AMR) occurs when microbes undergo changes that render antimicrobial drugs ineffective against them, resulting in limited, more expensive treatment options, longer hospital stays, and increased mortality rates. No study has estimated the costs related to AMR in hospitals in Pakistan. This study was conducted to determine the financial burden of antimicrobial resistance (AMR) in Pakistan and to compare it with the additional costs incurred by patients who respond well to antimicrobial treatments. The study also aimed to identify the most frequent types of microbes that cause bloodstream infections in Pakistan.MethodsThis quantitative study was conducted employing a prospective cohort study design. A sample of 193 patients was selected from two public sector tertiary care hospitals in the twin cities of Islamabad and Rawalpindi for a period of 7 months. The frequency trends of antimicrobial resistance against 12 blood pathogens were determined by analyzing culture sensitivity reports from patients who tested positive, as provided by pathology laboratories of the study hospitals. Direct and indirect costs were calculated using data from patients’ medical records and through direct interactions with patients.ResultsThis study estimated that treating cases of AMR resulted in approximately USD 33.97 [Pakistani Rupees (PKR) 9483.2] in additional costs compared to treating susceptible infections due to extended lengths of hospital stays. However, indirect costs such as spending on food, productivity loss, and accommodation are USD 55.84 (PKR 15588.3) higher in the non-infected control cohort compared to the cases. Direct costs (transport, pharmacy, and laboratory expenses) are directly related to AMR and add an additional burden of USD 12.30 (PKR 3435) for cases compared to non-infected controls. In comparison to susceptible controls, cases incur an additional cost of USD 32.9 (PKR 9185.9).ConclusionThis study helped predict the economic burden of antimicrobial resistance in admitted patients with bloodstream infections (BSIs) in low- and middle-income countries, such as Pakistan, by different variable cost estimates. These findings will help in designing the most appropriate approach to combat AMR. Additionally, this study serves as a baseline tool that can be extrapolated to estimate the national economic burden because of AMR.

ObjectiveProviding quality healthcare is an essential part of the healthcare system. The high workload and night work associated with healthcare providing may result in work-life imbalance among healthcare professionals (HCPs) and in degradation in the quality of care.MethodsThis cross-sectional study aimed to assess the effects of sociodemographic characteristics and shift work on HCPs’ well-being in four large hospitals in the United Arab Emirates using a validated questionnaire.ResultsResponses from 526 participants indicated that 79.2% of them were under the age of 40, 70.2% were females and 50.2% were single or divorced. Responses indicated that many HCPs reported engaging in unhealthy behaviors such as consuming energy drinks (37.3%), smoking (14.2%) and taking stimulant pills (5.7%) with males being more susceptible to these practices compared to females. Results also showed that participants perceived their overall health rate, on the average, to be moderate with one third of participants indicating to be overweight. Moreover, results showed that many participants reported having blood pressure issues (16%), diabetes (8.6%) and/or heart diseases (2.7%), with females more prone to these diseases than males. Another important finding was that most respondents reported sleeping significantly less than the recommended duration and taking too long time to fall asleep. Finally, results revealed that HCPs on 12-h shifts indicated having greater satisfaction but tend to experience more exhaustion levels and worsened health indicators than those on 8-h shifts.ConclusionHCPs work has adverse effects on their well-being especially when combined with working at night. Healthcare implications of the results as well as recommendations to improve the well-being of HCPs based on the findings are given at the end.

ObjectiveThis study aims to provide a deeper understanding of what persons with lived experience and professionals with experience of patient safety, suicide research, and investigations consider to be most important in investigations of healthcare before suicide to learn and improve the care of suicidal patients.MethodThis is a qualitative study based on 15 semistructured interviews with persons with lived experience of suicidality and professionals. Thematic analysis was used.ResultsThe persons with lived experience and the professionals agreed that a holistic approach to the investigations is crucial. They should embrace a longer period of time, involve family and significant others, integrate the perspective and expectations of the patient, and analyze factors of significance for suicidality, suicide prevention, and safety. There is a need to improve the investigations through the involvement of all stakeholders and actors, securing competence in the investigation team and prioritizing cases to investigate.ConclusionsSubstantial changes in the approach and performance of investigations of suicide in healthcare are needed to make these investigations valuable for increasing the safety of the care of suicidal patients. A holistic perspective during the analysis is crucial for understanding the suicidal process, the interacting factors, and the care process preceding suicide. Competencies in suicidality, suicide prevention, and patient safety must be included in the analysis team to ensure high quality and relevance. To improve the value of these investigations, we suggest establishing a template based on current knowledge to ensure attention to variables of significance for a safe care of suicidal patients.

IntroductionThe particle size characteristics of irregular sediments in the Yangtze River Source Area (YRSA) are pivotal for understanding the mechanical properties of the sedimentary medium.MethodsThis study utilizes field sediment sampling, laser scanning, laboratory testing, and mathematical statistics to analyze the morphological, geometric, mineralogical, and accumulation characteristics of sediment particles in the region.ResultsOur findings indicate that sediments in the YRSA have angular edges and deviate from spherical shapes, exhibiting elongated and flatter three-dimensional morphologies. In the experiment, the sliding plate method was used to measure the angle of repose of the sediments, which was found to be 36.7° above water and 35.9° below water. Both values are higher than the typical range for non-plateau regions, indicating reduced sediment mobility. The sediments are composed of fine-grained and coarse-grained soils. The particle size distribution is primarily coarse sand (0.5-2.0 mm), fine gravel (2.0-5.0 mm), and medium gravel (5.0-20.0 mm), with a significant coarsening trend observed over the past six years. The mineral composition, dominated by quartz, feldspar, and heavy minerals, is stable, with approximately 70% of the minerals having a hardness of ≥ 7 on the Mohs scale. The most abundant trace elements are Ti, Mn, Ba, P, Sr, Zr, and Cl.DiscussionThis research reveals that the sediment characteristics in the YRSA are markedly different from those of natural sands in non-plateau regions, necessitating a reevaluation of conventional theories and engineering practices for engineering constructions in this area. The insights from this study are profound and practically relevant, illuminating the sediment transport dynamics in alpine river systems and supporting sustainable regional development.

Published: February 2025

IntroductionArtistic swimming is a highly technical sport that requires a large volume of training and forced positions that generate a high risk of injury.Objectiveto compile scientific evidence on the incidence of injuries in artistic swimming. Literature study: PubMed, Web of Science, and SPORTDiscus databases were used to search for studies that analysed the epidemiology of injuries in artistic swimmers of any age and gender until June 2024. Methodology: the methodological quality of the studies was analysed with the Strengthening the Reporting Scale of Observational Studies in Epidemiology (STROBE) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) were followed. Synthesis: eleven studies met the inclusion criteria showing a clear trend of joint-ligament or muscle-tendon injuries in the shoulders, back, and knees.Conclusionsdespite the publication of an injury surveillance document and a consensus on data collection and injury surveillance, there are methodological limitations that do not allow firm conclusions to be drawn. More epidemiological studies that follow data collection and injury surveillance guidelines are needed to establish differences by gender, age groups, and test.

Published: February 2025

BackgroundHydrocephalus is a condition characterized by the accumulation of cerebrospinal fluid (CSF) in the ventricular system due to various causes, including excessive CSF production, impaired circulation, or absorption dysfunction. This condition is often accompanied by ventricular enlargement, compression of brain parenchyma, and increased intracranial pressure. Ventriculoperitoneal (VP) shunting is the first-line treatment for hydrocephalus; however, when the peritoneal catheter becomes obstructed due to encapsulation, the procedure may need to be converted to a ventriculoatrial (VA) shunt, which serves as a second-line treatment. Here, we present a case that demonstrates a rapid, simple, and minimally invasive technique for converting a VP shunt to a VA shunt. This approach eliminates the need to expose the retroauricular valve or disconnect the valve from the catheter, significantly reducing operative time and minimizing trauma.Case presentationA 61-year-old male patient presented with typical clinical features of hydrocephalus, including urinary dysfunction, gait instability, and gradually worsening cognitive decline over the course of a year, as well as corresponding imaging findings. The patient subsequently underwent a VP shunt procedure. However, within six months postoperatively, the patient experienced four episodes of shunt dysfunction due to omental encapsulation of the peritoneal catheter, leading to catheter obstruction and worsening hydrocephalus. During the first three episodes, the shunt catheter was released from omental encapsulation through laparoscopic surgery, providing temporary relief of hydrocephalus after each procedure. Following the fourth episode of peritoneal shunt dysfunction, we employed a rapid exchange technique to relocate the peritoneal catheter to the superior vena cava while preserving the ventricular catheter and shunt valve. Postoperatively, the patient's hydrocephalus-related symptoms gradually improved. At the three-month follow-up, the patient's hydrocephalus showed significant improvement, and he had returned to independent daily living.ConclusionThe rapid exchange technique is a fast, simple, and minimally invasive method for converting a VP shunt to a VA shunt, offering significant benefits in clinical practice.

BackgroundPulmonary involvement of Non-Langerhans Cell Histiocytosis (PNLCH) is a rare cause of interstitial pulmonary disease in people and are classified as either Erdheim-Chester disease (ECD) or Rosai-Dorfman disease (RDD). In veterinary medicine, feline pulmonary Langerhans cell histiocytosis (PLCH) has been identified as an infiltrative histiocytic disorder with an insidious onset of progressive respiratory distress and is non-responsiveness to empiric therapies. Unfortunately, subsequent death either from respiratory failure or humane euthanasia are the reported outcomes in all reported cases. To date, a similar primarily pulmonary histiocytic disease has not been described in dogs. We present a case of an 8-year-old male intact Rottweiler with acute, progressive respiratory failure with a post-mortem diagnosis of PNLCH.Case summaryAn 8-year-old male intact Rottweiler presented following approximately 2 weeks of lethargy, anorexia, hypersalivation, and progressive respiratory distress characterized by intermittent wheezing, increasing inspiratory and expiratory effort, and tachypnea. Diagnostic imaging demonstrated a multifocal cranioventral alveolar pattern with nodules in the lung periphery. There were no significant changes appreciated in bloodwork. Despite empiric antimicrobials, oxygen support, and other supportive care measures, the patient continued to deteriorate and was subsequently euthanized. Post-mortem analysis was confirmatory for single-organ PNLCH.New or unique information providedThis case report represents the first reported case of canine PNLCH. Additionally, this report also provides further characterization of PNLCH in dogs with ante-mortem diagnostic imaging, cytologic evaluation of lung tissue, and post-mortem immunohistochemical characterization of canine PNLCH.

Published: February 2025

Development of any trait-directed selection strategy requires basic knowledge about some important population-specific parameters such as the effective population size Ne and genetic connectedness among flocks. The Ne, as an indirect measure of genetic variability, is important for the conservation of the genome, while genetic connectedness is necessary for unbiased across-flock genetic evaluation. The average number of full generations (NFG) in the reference population of the Pag sheep under selection for dairy traits was 3.05. The Ne estimated from individual coancestry rate ∆Cij in the last generation was 127 animals, and the average prediction error variance of the difference in EBVs between animals belonging to different flocks (PEVDi′,j′ ¯) was 0.81. Although conceptually different, these two population genetic parameters may be related in the populations under selection. Although it is difficult to prove this hypothesis, we decided to test it by regressing the partial (generational) estimates of Ne on PEVDi′,j′ ¯. It was estimated that ∆PEVDi′,j′ ¯ of −0.01 was accompanied by ∆Ne of +5.5 animals. The results suggest that strengthening genetic connectedness among flocks in populations might have a positive impact on genetic diversity; however, more research is needed before generalization.

Thermal refuges in streams are essential for the survival of coldwater fish species such as Redband trout (Oncorhynchus mykiss) in landscapes with stressful or lethal stream temperatures. We utilized an uncrewed aerial system (UAS) mounted with thermal and natural color sensors to conduct hourly flights over a 24 h period in the desert stream Little Jacks Creek during late summer when temperatures were near seasonal maximums and streamflow was near seasonal minimums. We used fine-resolution imagery to map stream temperatures and characterize how our thermal sensor exhibits variability across a diel period in an environment where thermal sensor viability had not yet been assessed. Thermal imagery from 3 out of 24 flights showed no significant differences when compared to true water temperatures from in-stream temperature loggers, which appeared to be highly dependent on atmospheric conditions. The thermal imagery (range of 9.17 to 21.04 °C) consistently underestimated HOBO logger stream temperatures (range of 13.6 to 17.1 °C) during cooler, nighttime flights and overestimated temperatures during hotter, afternoon hours, resulting in a global RMSE of 2.12 °C. Between-flight RMSE values ranged from 0.53 °C to 4.00 °C, within the error range of the thermal sensor. The thermal data support existing findings of optimal hours for flying UAS thermal surveys and showed specific patterns in TIR sensor accuracy that were dependent on the time of flight. This study yields valuable lessons for future stream temperature data collection in environments with highly variable temperatures, aiding in the calibration of thermal sensors on UAS missions. Furthermore, our results provide insights into environmental stressors such as increased stream temperatures, which is vital for conservation efforts for organisms that rely on coldwater refuges within desert streams.

Background/Objectives: BRAFV600E-mutant colorectal cancer (CRC) is associated with poor prognosis, and despite the introduction of BEACON therapy, significant treatment challenges remain. This study investigates the clinical utility of BRAFV600E in cell-free DNA (cfDNA BRAFV600E) as a biomarker for real-time treatment monitoring in metastatic cases and for evaluating minimal residual disease (MRD) after curative resection. Methods: This single-center, prospective observational study included 37 patients with BRAFV600E-mutant CRC treated at Nippon Medical School Hospital between April 2017 and June 2024. Patients were divided into two cohorts: Cohort 1 (Stage IV cases): Evaluated cfDNA BRAFV600E for treatment monitoring. Cohort 2 (Stage I–III curatively resected cases): Assessed cfDNA BRAFV600E for recurrence risk prediction. Blood samples were collected before and during treatment and analyzed using droplet digital PCR (ddPCR) to measure cfDNA BRAFV600E levels. Results: Cohort 1 (Stage IV, n = 14): Pre-treatment cfDNA BRAFV600E was detected in 93% of cases. Patients with a decrease in cfDNA BRAFV600E variant allele frequency (VAF) after chemotherapy had significantly longer overall survival (511 vs. 189 days, p = 0.03) than those without a decrease. Cohort 2 (curatively resected, n = 23): cfDNA BRAFV600E was detected in 4/23 patients (17.4%) at 1 month post-surgery. cfDNA BRAFV600E showed better recurrence prediction compared to CEA (100% vs. 18.8%, p = 0.004). Among the seven patients who experienced recurrence, those with postoperative cfDNA BRAFV600E positivity had significantly shorter disease-free survival compared to cfDNA BRAFV600E-negative patients (179 vs. 840 days, p = 0.04). Conclusions: These findings support cfDNA BRAFV600E as a promising biomarker for monitoring treatment response and MRD detection in BRAFV600E-mutant CRC, reinforcing its role in guiding personalized treatment strategies and postoperative surveillance.
