ABSTRACT

BACKGROUND: The increasing prevalence of moral distress in the stressful environment of the intensive care unit (ICU) provides grounds for nursing error and endangers patients’ health, safety, and even life. One of the most important reasons for this distress is the treatment team’s second victim syndrome (SVS), especially nurses, following errors in the treatment system.

OBJECTIVES: The present study aimed to determine the relationship between moral distress and SVS in ICUs.

RESEARCH DESIGN: This cross-sectional study involved a sample size of 96 ICU nurses working in hospitals affiliated with Tehran University of Medical Sciences, Iran, in the 2021-2022 period, who were selected via a simple random sampling method. Data were collected using the Demographic Questionnaire, the second victim experience and support tool (SVEST) and Moral Distress Scale-Revised (MDS-R). Descriptive statistics (percentage, frequency, mean, and SD) and analytical tests (Spearman correlation coefficient test, independent t-test, and ANOVA) were employed for data analysis.

PARTICIPANTS AND RESEARCH CONTEXT: This study used a sample size of 96 intensive care unit nurses working in hospitals affiliated to Tehran University of Medical Sciences selected by simple random sampling.

ETHICAL CONSIDERATIONS: The study obtained research ethics approval, and all participants were informed of the voluntary and anonymous nature of their participation.

FINDINGS: The results showed that 59.4% of nurses suffered a low level of moral distress, and 40.6% suffered from a moderate level of moral distress. The SVS score of 86.5% of the nurses was moderate. There was no significant and direct correlation between moral distress and SVS in nurses; however, there was a significant and inverse correlation between the moral distress intensity and SVS (p = 0.011).

CONCLUSION: Despite no significant correlation between moral distress and SVS, these variables were at moderate levels. Accordingly, it is suggested to provide a proper ground for expressing morally stressful situations, counseling and training strategies to deal with moral distress, creating support resources for those suffering from SVS, and implementing empowerment programs.

ABSTRACT

PURPOSE: To evaluate the technical, radiological, and clinical outcomes after type 2 endoleak (T2EL) embolization in patients with a growing aneurysm sac after endovascular aortic aneurysm repair (EVAR). Additionally, to determine clinical and imaging-based factors for outcome prediction after embolization of a T2EL.

METHODS: A single-institution, retrospective analysis was performed of 60 patients who underwent a T2EL embolization procedure between September 2005 and August 2016 to treat a growing aneurysm sac diameter following EVAR. The patients’ electronic medical records and all available pre- and post-embolization imaging were reviewed. Statistical analysis methods included logistic regression models for binary outcomes, proportional odds models for ordinal outcomes, and linear regression models for continuous outcomes. The Kaplan-Meier method was used to estimate the overall survival probability.

RESULTS: Technical, radiological, and clinical success rates after T2EL embolization were 95% (n = 57), 26.7% (n = 16), and 76.7% (n = 46), respectively. Persistent aneurysm sac expansion was found in 31 patients (51.7%). Unsharp or blurred T2EL delineation on pre-interventional computed tomography (CT) was a predictive factor for a post-embolization persistent visible endoleak and persistent growth of the aneurysm sac (P = 0.025). Median survival after T2EL embolization was 5.35 years, with no difference observed between patients with persistent sac expansion compared with patients with stable or decreased sac diameter.

CONCLUSION: Progression of the aneurysm sac diameter was observed in half the study patients, despite technically successful T2EL embolization. Unsharp or blurred T2EL delineation on pre-interventional CT seemed to be an imaging-based predictor for a persistent T2EL and progressive aneurysm sac growth after embolization.

ABSTRACT

OBJECTIVE: Men are less likely than women to engage with formal mental health services for suicidality. We describe the sources of support, barriers to service use, and coping strategies of men with past-year suicidal ideation who are not receiving formal mental health services.

METHOD: Australian men experiencing past-year suicidal ideation who also did not receive formal mental health services within the past year (n = 176) completed a survey that assessed help-seeking behaviors, coping strategies and styles, use of general services, barriers to service use, and individual-level characteristics. Analyses included descriptive statistics and bivariate analyses.

RESULTS: The most common type of support was self-help resources, and self-reliance was the most common barrier to formal mental health service use. Most participants had seen a GP for non-mental-health-related reasons in the past year. Men who did not seek any help for their suicidality experienced lower instrumental barriers and perceived need for support, and lower levels of certain coping styles. Limitations included a cross-sectional design and small sample size.

CONCLUSION: The current study provides insight into the help-seeking experiences of men with past-year suicidality and not receiving formal mental health services. The findings suggest it may be helpful to improve the linkage between online and informal sources of support and evidence-based interventions.HIGHLIGHTSOnline self-help, friends, and partners were the most commonly used sources of help.A subset of men (42%) with lower perceived need for help did not seek any support.Despite no past-year formal mental health service use, 80% of the men had seen a GP.

ABSTRACT

Understanding the neurodegenerative mechanisms underlying cognitive decline in the general population may facilitate early detection of adverse health outcomes in late life. This study investigates genetic links between brain morphometry, ageing and cognitive ability. We develop Genomic Principal Components Analysis (Genomic PCA) to model general dimensions of brain-wide morphometry at the level of their underlying genetic architecture. Genomic PCA is applied to genome-wide association data for 83 brain-wide volumes (36,778 UK Biobank participants) and we extract genomic principal components (PCs) to capture global dimensions of genetic covariance across brain regions (unlike ancestral PCs that index genetic similarity between participants). Using linkage disequilibrium score regression, we estimate genetic overlap between those general brain dimensions and cognitive ageing. The first genetic PCs underlying the morphometric organisation of 83 brain-wide regions accounted for substantial genetic variance (R² = 40%) with the pattern of component loadings corresponding closely to those obtained from phenotypic analyses. Genetically more central regions to overall brain structure – specifically frontal and parietal volumes thought to be part of the central executive network – tended to be somewhat more susceptible towards age (r = -0.27). We demonstrate the moderate genetic overlap between the first PC underlying each of several structural brain networks and general cognitive ability (r_g = 0.17-0.21), which was not specific to a particular subset of the canonical networks examined. We provide a multivariate framework integrating covariance across multiple brain regions and the genome, revealing moderate shared genetic etiology between brain-wide morphometry and cognitive ageing.

ABSTRACT

The aim of the study was to examine the effect of parents’ life position on the prediction of behavioral problems of preschool children. The sample of the study consisted of 364 children enrolled in independent kindergartens and preschools of primary schools affiliated to Altındağ District Directorate of National Education in Turkey and their parents (290 mothers and 97 fathers). In the study, the survey model, which aims to determine the current situation among quantitative research methods, and the relational model, which aims to reveal the link between two or more variables and the strength of the link, were used (Frankel et al., 2011). The data obtained from the study in which “Family Information Form, Preschool and Kindergarten Behavior Scale and Life Positions Scale” were used as data collection tools were analyzed with Pearson Correlation Coefficient and Multiple Regression analysis methods. When the findings of the research were examined, it was found that as the “I am Okey, You are Okey” life position of the parents increased, the children’s total behavior problems, which consisted of internalizing, externalizing and a combination of internalizing and externalizing behavior problems, decreased whereas “I am not Okey, You are Okey” and “I am not Okey, You are not Okey” life positions increased, the children’s internalizing, externalizing and total behavior problems increased. Moreover, the regression analysis results of the study showed that parents’ life positions had a statistically significant effect in predicting their children’s behavior problems.

ABSTRACT

Objective:To explore the clinical correlation between peripheral blood basophil levels and chronic sinusitis （CRS） subtypes. Methods:One hundred and twenty-six patients with CRS and 103 healthy cases from physical examination admitted to the First Affiliated Hospital of Soochow University from January 2021 to October 2022 were retrospectively analyzed. According to the histopathological classification, CRS patients were divided into eosinophilic chronic sinusitis （eCRS） group （47 cases） and non eosinophilic chronic sinusitis （non-eCRS） group （79 cases）. The differences among the three groups in peripheral blood inflammation cell counts, eosinophils-to-basophils ratio（bEBR）, basophils-to-neutrophils ratio（BNR）, basophils-to-lymphocytes ratio（BLR）, basophils-to-monocytes ratio（BMR） were compared, and study the correlation between each index and Lund-Mackay score, and the correlation between basophils in peripheral blood and other inflammatory cells. Results:The counts of basophils in the peripheral blood of the healthy control group, eCRS group and non-eCRS group were 0.03±0.01, 0.04±0.02, 0.03±0.02, respectively, the eosinophils-to-basophils ratio（bEBR） were 5.64±4.22, 8.38±5.95, 4.55±3.90, the basophils-to-neutrophils ratio（BNR） were 0.01±0, 0.01±0.01, 0.01±0.01, and the basophils-to-lymphocytes ratio（BLR） were 0.01±0.01, 0.02±0.01, and 0.02±0.01, respectively, the basophils-to-monocytes ratio（BMR） were 0.08±0.04, 0.11±0.06, and 0.08 ±0.04 respectively. There was a statistically significant difference between eCRS group and healthy control group, non-eCRS group（P<0.01）, while there was no statistically significant difference between non-eCRS group and healthy control group（P>0.05）. Basophil counts （r=0.185 5, P<0.05）, BLR（r=0.226 9, P<0.05）, BMR（r=0.228 1, P<0.01） in patients with CRS were positively correlated with Lund Makey score. In addition, basophils were also positively correlated with eosinophils（r=0.479 2, P<0.01）, lymphocytes（r=0.259 4, P<0.01）, and monocytes（r=0.256 4, P<0.01） in patients with CRS. Conclusion:The peripheral blood basophil count, BLR and BMR were significantly increased in eCRS, and were significantly positively correlated with Lund -Makey score. It has the potential to develop into disease biomarkers and new therapeutic targets of eCRS.

ABSTRACT

Objective:To explore the safety and feasibility of bilateral axillo-breast approach （BABA） robot in the operation of thyroid cancer in obese women. Methods:The clinical data of 81 obese female patients who underwent da Vinci robotic thyroid cancer surgery（robotic group） at the Department of Thyroid and Breast Surgery, PLA 960 Hospital from May 2018 to December 2021 were retrospectively analyzed and compared with the clinical data of 106 obese female thyroid cancer patients who underwent open surgery（open group） during the same period. The age, body mass index（BMI）, mean time of surgery, mean postoperative drainage, tumor diameter, postoperative tumor stage, number of lymph node dissection in the central and lateral cervical regions, number of positive lymph nodes in the central and lateral cervical regions, postoperative cosmetic outcome satisfaction score, mean postoperative hospital stay and postoperative complications of all patients were counted. The results were analyzed using SPSS 26.0 statistical software, and the count data were compared using the χ² test, and the measurement data were compared using the t test. Results:All patients completed the operation successfully, and there was no conversion in the robot group, postoperative pathological results were all composed of papillary thyroid carcinoma. The operation time in the robot group was（144.62±36.38） min, which was longer than that in the open group（117.06±18.72） min（P<0.05）. The average age of the robot group was（40.25±9.27） years, which was lower than that of the open group（49.59±8.70） years（P<0.05）. The satisfactory score of cosmetic effect in the robot group（9.44±0.65） was higher than that in the open group（5.23±1.07）（P<0.05）. There was no significant difference in tumor diameter, BMI, average postoperative drainage, temporary hypoparathyroidism and recurrent laryngeal nerve injury, number of central and lateral cervical lymph node dissection, number of positive lymph nodes in the central and lateral cervical regions, and average postoperative hospital stay between the two groups. There was no permanent hypoparathyroidism and recurrent laryngeal nerve injury in both groups. Conclusion:The application of BABA pathway robot in thyroid cancer surgery in obese women is safe and feasible, and the cosmetic effect is better after operation.

ABSTRACT

Objective:To investigate the compliance of patients with allergic rhinitis（AR） receiving sublingual immunotherapy and its influencing factors. Methods:The clinical data of 291 AR patients who received sublingual immunotherapy for dust mites at the First Hospital of Peking University from January 2016 to January 2018 were retrospectively analyzed, and their outpatient or telephone follow-up was conducted. For patients whose treatment time was less than 2 years, the time and reason for the loss were recorded, and the factors affecting their compliance were discussed from the aspects of gender, age, and education. Results:Among the 291 patients, 245 cases（84.2%） were successfully followed up, and 193 cases（78.8%） fell off midway（treatment time<2 years）. The overall compliance rate was 21.22%（52/245）. The compliance rate of children is higher than that of adults（χ²=21.306, P<0.05）, and gender and education level have no significant effect on the compliance rate. The time period for the largest number of shedding was 6-<12 months after treatment（68 cases, 27.8%）. The main cause of shedding was symptom relief, which was considered cured（16.7%）. Secondly, within 3 months after treatment, a total of 61 patients（24.9%） fell off, of which 34 cases（13.9%） fell off because of troublesome medication, often missed medication, and simply stopped taking the drug. Statistics on the overall reasons for shedding in 193 patients, the top three shedding reasons were: cured after symptom relief（59 cases, 30.6%）, troublesome medication, discontinuation after missed dose（44 cases, 22.8%）, slow onset or ineffectiveness（26 cases, 13.5%）. Conclusion:The overall compliance of sublingual immunotherapy in patients with allergic rhinitis is poor, and the compliance of children is better than that of adults. Clinicians should focus on the reasons for patients to fall off at various times, strengthen patient education, enhance patient confidence in treatment, and improve the compliance of patients.

ABSTRACT

Objective:To prepare PLGA nanoparticles loaded with Der f 1/IGF-1（Der f 1/IGF-1 NPs） and investigate their role in promoting the formation of Treg cells. Methods:NPs coated with Der f 1/IGF-1 were prepared by double emulsion method and their physicochemical properties and cumulative release rate in vitro were analyzed. After pretreatment, BMDC was divided into Saline group, Blank NPs group, Der f 1/IGF-1 group and Der f 1/IGF-1 NPs group. Determination of the expression of IL-10 and TGF-β in BMDC by ELISA. The number of Treg cells was detected by flow cytometry. Results:The results showed that Der f 1/IGF-1 NPs were spherical structures, with good dispersion, particle size less than 200 nm, negative charge and stable slow-release effect of Zeta potential. After BMDC pretreatment, the expression levels of TGF-β and IL-10 in BMDC cells in the Der f 1/IGF-1 NPs group were significantly increased compared with the Blank NPs group, and the difference was statistically significant（P<0.001）. After co-culture with CD4+ T cells, the proportion of Treg cells produced in the Der f 1/IGF-1 NPs group was significantly increased, and the difference was statistically significant（P<0.001）. Conclusion:Der f 1/IGF-1 NPs can induce Treg cell generation in vitro. This study provides a new and more effective method for the reconstruction of immune tolerance dysfunction.

ABSTRACT

Objective:To evaluate the influence of an additional roll test on the repositioning procedure by SRM-vertigo diagnosis system for horizontal canal benign paroxysmal positional vertigo（HC-BPPV）. Methods:A total of 713 patients diagnosed with HC-BPPV in Department of Otolaryngology Head and Neck Surgery，the First Affiliated Hospital of Xi’an Jiaotong University from Jan 2020 to Feb 2022 were enrolled. The patients were divided into two groups by hospital card numbers, in which the number is odd were considered as group A, and the number is even were considered as group B. The group A underwent two circles of Barbecue repositioning procedure by SRM-vertigo diagnosis system, while the group B first performed an additional roll test and then underwent two circles of Barbecue repositioning procedure by SRM-vertigo diagnosis system, to observe the cure rate and compare influence of HC-BPPV by an additional roll test. The quality of life and sleep of patients before and one-month after the treatment were assessed by the dizziness handicap inventory（DHI） and the pittsburgh sleep quality（PSQI）. Results:The cure rate of group A was 63.21%, and the cure rate of group B was 87.68%，the difference between the two groups was statistically significant（P<0.05）; The DHI score of patients after the repositioning was significantly lower than that before the repositioning（P<0.05）. The PSQI score after the repositioning was significantly lower than that before the repositioning（P<0.05）. The DHI and the PSQI scores after the repositioning were significantly lower than that before the repositioning, with a statistically significant difference （P< 0.05）. The total score of DHI in group B after treatment was lower than that in group A, with a statistically significant difference（P<0.05）. The total score of PSQI in group B after treatment was lower than that in group A, with non-statistically significant difference （P< 0.05）. Conclusion:An additional roll test before the repositioning procedure by SRM-vertigo diagnosis system can significantly improve the cure rate of HC-BPPV, relieve anxiety, and improve the quality of life.
