Authors: Stickley Andrew , Shirama Aya , Sumiyoshi Tomiki 
Published: June 2023

Background: Research has shown that discrimination is prevalent in many countries and associated with poorer mental health. However, little is known about discrimination and its effects in Japan. Aims: To address this deficit this study examined the association between perceived discrimination and mental health outcomes in the Japanese general population and the role of general stress in these associations. Method: Data were analyzed from 1,245 individuals (age 18–89) that were collected in an online survey in 2021. Perceived discrimination was assessed with a single-item measure as was lifetime suicidal ideation. Depressive and anxiety symptoms were respectively measured with the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) scale. General stress was assessed with the Perceived Stress Scale (PSS-14). Logistic regression was used to assess associations. Results: Perceived discrimination was prevalent (31.6%) in the study sample. In fully adjusted analyses discrimination was associated with all of the mental health outcomes/general stress with odds ratios (ORs) ranging from 2.78 (suicidal ideation) to 6.09 (general stress) among individuals with a high level of discrimination. When the analyses were adjusted for general stress (as a continuous score) there was a large reduction in the ORs although high discrimination continued to be significantly associated with anxiety (OR: 2.21), while a mid level of discrimination was related to depressive symptoms (OR: 1.87) and had a borderline association with suicidal ideation. Conclusion: Perceived discrimination is common in the Japanese general population and associated with worse mental health, with stress possibly playing a role in this association.

Published: June 2023

Background: Mental health stigma is a relevant phenomenon with implications for the people who suffer from it. Despite its importance, no studies have been carried out in Spain at national level with a representative sample of the population. Aims: The aim of this research is to analyze the stigma associated with MHPs in a representative sample of the Spanish population for the first time. Method: A cross-sectional quantitative descriptive study was carried out with a representative sample of the population ( N = 2746). Descriptive analyses and regressions are carried out on the different dimensions of stigma such as attitude, attribution and intention of social distance. Results: Medium levels of stigma are obtained in stigmatizing attitudes and attributions, and medium-low levels in the intention of social distance. The best predictors of stigma in its different dimensions are attitudes, attributions and intention of social distance themselves. Progressive political ideology is related to less stigma in all dimensions. Knowing someone with mental health problems and talking openly about it together with higher education are also relevant protectors. Mixed results are obtained regarding age, gender and help-seeking. Conclusion: National programs and campaigns focused on attitudes, attributions and behavioral intentions are necessary to reduce the stigma still present in Spanish society.
Implicit Theories of Emotional Intelligence and Students’ Emotional and Academic Outcomes
Authors: Costa Ana , Faria Luísa 
Published: June 2023

In this study, we addressed the relevance of implicit theories of emotional intelligence (ITEI) to students’ emotional and academic outcomes throughout secondary school. During a three-wave longitudinal survey (10th–12th grades), 222 students, ages 14–18 years old at the first round of data collection ( Mage = 15.4, SD = 0.63) and mostly female (58.6%), completed questionnaires on ITEI, emotional intelligence (EI; ability and trait), and emotions towards school. The results provided evidence for the relation of ITEI with EI (ability and trait) in the following year and their extended link with students’ emotions towards school and academic achievement (Portuguese academic grade) at the end of secondary school. In addition, ability and trait EI mediated the link of entity ITEI and negative emotions and achievement. The findings suggest the importance of fostering more dynamic ITEI among students as a mean for enhancing emotional and academic outcomes.

Published: June 2023

Background: Ankle fragility fractures (AFX) continue to increase in the elderly population. There is limited knowledge of AFX characteristics compared to nonankle fragility fractures (NAFX). The American Orthopaedic Association’s Own the Bone (OTB) is a fragility fracture initiative. This robust data set was used to examine and compare characteristics of patients presenting with AFX to those with NAFX. Methods: The OTB database contained 72,617 fragility fractures between January 2009 and March of 2022 and were reviewed in our secondary cohort comparative analysis. After exclusions, AFX accounted for 3229 patients and 54,772 patients were in the NAFX cohort. Bivariate analysis and logistic regression compared the AFX and NAFX groups concerning demographics, bone health factors, medication use, and prior fragility fracture. Results: AFX patients were found to have a higher likelihood to be younger (67.6 years old), female (81.4%), non-Caucasian (11.7%) and have a higher BMI (30.6) compared to NAFX. Prior AFX predicted the risk of a future AFX. The probability of an AFX increased with increased age and BMI. Conclusion: A prior AFX is independently predictive of subsequent AFX. Therefore, these fractures should be considered a sentinel event. These patients are more likely to have higher BMI, to be of female gender, non-Caucasian race, and are younger compared to patients with NAFX. Level of Evidence: Level III, retrospective cohort.
Research on the influence of check valve on noise performance of variable frequency scroll refrigeration compressor

Published: June 2023

Check valve is one of the core components of the scroll refrigeration compressor, which can directly affect its efficiency, life, and noise performance. Traditional check valve is the reed valve. This paper deeply studies the dynamic characteristics of reed valve and reveals the main reason of the valve noise under different rotation speeds. The large noise is mainly attributing to the large pressure pulsation as well as fast circulation velocity of fluid and the severe slapping of the reed plate on the valve seat, which is influenced by the high pressure ratio of the working condition and stiffness of the reed valve. In order to reduce the noise of the check valve, the circular valve is designed to replace reed valve in this paper. At each rotation speed, the circular valve shows a continuous exhaust process, which avoids the slapping of the valve plate on the valve seat. More importantly, the exhaust is smooth and the pressure pulsation as well as the flow rate of the fluid is reduced significantly leading to the low aerodynamic noise. Therefore, compared with the reed valve compressor, the sound pressure level of the circular valve compressor at 1800, 4200, and 6600 rpm is decreased by 3.0, 5.2, and 0.3 dB, respectively.

Published: June 2023

Purpose: To determine whether the STOP-Bang questionnaire, which is a tool for evaluating obstructive sleep apnea, is associated with aortic remodeling after thoracic endovascular aortic repair (TEVAR) in patients with type B aortic dissection (TBAD). Methods: Patients with TBAD who underwent standard TEVAR at our center from January 2015 to December 2020 were enrolled. For the included patients, we recorded baseline characteristics, comorbidities, preoperative computed tomographic angiography findings, procedure details, and complications. The STOP-Bang questionnaire was administered to each patient. Total scores comprised points for 4 yes/no questions and 4 clinical measurements. STOP-Bang ≥5 and STOP-Bang <5 groups were then created using the STOP-Bang total scores. We evaluated aortic remodeling 1 year after discharge and the reintervention rate, as well as false lumen complete thrombosis (FLCT) and non-FLCT length. Results: Fifty-five patients were enrolled in the study; STOP-Bang <5, n=36, and STOP-Bang ≥5, n=19. Compared with the STOP-Bang ≥5 group, the STOP-Bang <5 group achieved statistically significantly higher descending aorta positive aortic remodeling (PAR) rates in zones 3 to 5 (zone 3: p=0.002; zone 4: p=0.039; zone 5: p=0.023), higher total descending aorta-PAR rate (66.7% vs 36.8%, respectively; p=0.004), and lower reintervention rate (8.1% vs 38.9%, respectively; p=0.005). In the logistic regression analysis, STOP-Bang ≥5 had an odds ratio of 0.12 (95% confidence interval: 0.03–0.58; p=0.008). There was no significant difference in overall survival between the groups. Conclusion: STOP-Bang questionnaire scores were associated with aortic remodeling after TEVAR in patients with TBAD. Increasing the frequency of surveillance after TEVAR might be beneficial in these patients. Clinical Impact We analysed aortic remodelling 1 year after thoracic endovascular aortic repair (TEVAR) in acute type B aortic dissection (TBAD) patients with STOP-Bang < 5 and STOP-Bang ≥ 5. Aortic remodelling was better, and the reintervention rate was higher in patients with STOP-Bang < 5 compared with patients with STOP-Bang ≥ 5. In patients with STOP-Bang ≥ 5, aortic remodelling was worse in zones 3–5 compared with zones 6–9. This study suggests that the STOP-Bang questionnaire results is associated with aortic remodelling after TEVAR in patients with TBAD.

Objectives: To analyze device designs, similarities and overlaps of custom-made fenestrated arch endografts intended for mid/distal arch thoracic endovascular aortic repair. Materials and Methods: A multicenter cross-sectional study analyzing custom-made anonymized graft plans was performed. Graft plans were included from a cohort of mid/distal aortic arch repairs using custom-made fenestrated aortic endografts treated at 8 centers. Grafts targeting >2 arteries were excluded. No patient/clinical data were analyzed. A descriptive analysis was performed followed by an analysis of overlap of the designs to reach a common design in which the greatest number of grafts would overlap. Results: One hundred thirty-one graft plans were included. All grafts were custom-made grafts from the COOK Medical Fenestrated arch platform. Ninety-four (71.8%) had a scallop-and-single-fenestration design, 33 (25.2%) had a single fenestration and 4 (4.3%) a single scallop. For analysis purposes, these latter 4 grafts were excluded. Two main graft plans ( Plans 1 and 2) were proposed after analysis with similar configuration (1 scallop with 30 mm width, 20 mm height, 12:00 position; 1 preloaded fenestration with 8 mm diameter, 26 mm from the top of the graft and 12:00 position; tapered, with a 193 mm length and 32 mm distal diameter) but with 2 different proximal diameters of 38 mm ( Plan 1) and 44 mm ( Plan 2), reaching an overall feasibility of 85.8% (n=109), being 47.2% (n=60) and 38.6% (n=49) for each design, respectively. Conclusion: The degree of overlap between the studied fenestrated and/or scalloped thoracic endovascular aneurysm repair (TEVAR) graft designs was high. Future studies analyzing these designs in a real-world cohort of patients are needed to further address off-the-shelf feasibility. Clinical Impact In a multicenter study analyzing 127 fenestrated aortic arch endograft plans from 9 aortic centers, we found that the degree of overlap between the studied fenestrated and/or scalloped arch graft designs was high and that 2 proposed graft designs would be theoretically applicable in 85.8% of cases. Future studies analyzing these designs in a real-world cohort of patients are needed to further address off-the-shelf feasibility.

Published: June 2023

Objectives To establish and validate a radiomics nomogram model for preoperative prediction of KIT exon 9 mutation status in patients with gastrointestinal stromal tumors (GISTs). Materials and methods Eighty-seven patients with pathologically confirmed GISTs were retrospectively enrolled in this study. Imaging and clinicopathological data were collected and randomly assigned to the training set (n = 60) and test set (n = 27) at a ratio of 7:3. Based on contrast-enhanced CT (CE-CT) arterial and venous phase images, the region of interest (ROI) of the tumors were manually drawn layer by layer, and the radiomics features were extracted. The intra-class correlation coefficient (ICC) was used to test the consistency between observers. Least absolute shrinkage and selection operator regression (LASSO) were used to further screen the features. The nomogram of integrated radiomics score (Rad-Score) and clinical risk factors (extra-gastric location and distant metastasis) was drawn on the basis of multivariate logistic regression. The area under the receiver operating characteristic (AUC) curve and decision curve analysis were used to evaluate the predictive efficiency of the nomogram, and the clinical benefits that the decision curve evaluation model may bring to patients. Results The selected radiomics features (arterial phase and venous phase features) were significantly correlated with the KIT exon 9 mutation status of GISTs. The AUC, sensitivity, specificity, and accuracy in the radiomics model were 0.863, 85.7%, 80.4%, and 85.0% for the training group (95% confidence interval [CI]: 0.750-0.938), and 0.883, 88.9%, 83.3%, and 81.5% for the test group (95% CI: 0.701-0.974), respectively. The AUC, sensitivity, specificity, and accuracy in the nomogram model were 0.902 (95% confidence interval [CI]: 0.798-0.964), 85.7%, 86.9%, and 91.7% for the training group, and 0.907 (95% CI: 0.732-0.984), 77.8%, 94.4%, and 88.9% for the test group, respectively. The decision curve showed the clinical application value of the radiomic nomogram. Conclusion The radiomics nomogram model based on CE-CT can effectively predict the KIT exon 9 mutation status of GISTs and may be used for selective gene analysis in the future, which is of great significance for the accurate treatment of GISTs.

Published: June 2023

Purpose/background The aim of this study was to evaluate the short and midterm results of aortic coarctation (AoCo) stenting in an adolescent and adult population. Methods All patients with a AoCo older than 14 years treated by stent placement between December 2000 and November 2016 were included in this study. Twenty-eight patients with an invasive peak systolic pressure gradient >20 mmHg were identified. Number of redilations, non-invasive systolic blood pressure, peak systolic pressure gradient, antihypertensive medication intake, claudication status and complications were evaluated. Results Twenty-two covered and 6 uncovered stents were successfully placed. Peak systolic pressure gradient decreased immediately after stenting from a mean of 32 mmHg to 0 mmHg (± 7 mmHg). Mean AoCo diameter increased from 8 tot 16 mm (± 4 mm). Peripheral arterial injury was seen in 2 patients (7.1%). The mean follow-up time was 60 ± 49 months. Redilation of the stent was required in 4 patients, 2 to accommodate for growth and 2 for restenosis. Six (35%) patients could stop all antihypertensive medication. All claudicants (6/28) became and remained asymptomatic after surgery and during their follow-up. No aneurysms, stent fractures or dissections were noticed. There were 2 stent migrations during the first procedure with only 1 needing additional stent placement. Conclusion Aortic coarctation stenting is a safe and effective treatment that significantly reduces the peak systolic pressure gradient. Antihypertensive medication can be reduced, and increase of walking distance in claudicants can be obtained. Younger patients may need more frequent reinterventions to accommodate for growth.

Published: June 2023

Objectives Ectopic breast cancer may present anywhere in the milk line, from the axilla to the groin which is extremely rare in the inguinal region. Despite morphologic differences, ectopic breast tissue presents characteristics related to orthotopic breast tissue in terms of function and pathologic degeneration. The case report describes the treatment of a unique ectopic breast carcinoma which was located in the inguinal region with a common femoral vein invasion. Methods We present a unique case of an ectopic breast carcinoma presenting in an unusual anatomic location along the milk line. The study was approved by the local Ethics Committee (protocol no: 12.01.2023-2023/02) Informed consent was obtained from the patient. Results The patient is surgically treated and supplemented with neoadjuvant chemotherapy,radiotherapy and endocrine therapy. Histopathological examination revealed the diagnosis of invasive ductal carcinoma. The right common femoral vein was reconstructed with bovine pericardial patch after totally removal of the mass. Conclusions This report alerts the reader to be cognizant of the unusual location of an ectopic breast cancer which was detected in the inguinal region with a common femoral vein invasion and discusses the treatment, suggesting novel therapeutic advice that could bring considerable clinical advantages. A multidisciplinary approach should be warranted in such cases to confirm a complete remission.

Aims: To determine the global and regional burden of stroke due to high temperature and the spatiotemporal trends in 204 countries and territories from 1990 to 2019. Methods: Based on Global Burden of Disease Study 2019, deaths, disability-adjusted life years (DALYs), and age-standardized mortality rate (ASMR) and age-standardized DALY rate (ASDR) for stroke attributable to high temperature (i.e. a daily mean temperature warmer than the theoretical minimum-risk exposure level (TMREL)) were calculated in global, geographical location, and country and analyzed by age, sex, subtypes, and socio-demographic index (SDI) from 1990 to 2019. The trends in ASMR and ASDR from 1990 to 2019 were estimated by linear regression model. The regression coefficients (β) referred to a mean change of per year for ASMR or ASDR attributable to high temperature. Results: The global burden of stroke attributable to high temperature had an increase trend from 1990 to 2019 (β = 0.005, 95% uncertainty interval (UI) = 0.003–0.007 for ASMR and β = 0.104, 95% UI = 0.066–0.142 for ASDR, respectively). Globally, in 2019, an estimated 0.048 million deaths and 1.01 million DALYs of stroke were attributable to high temperature, and the global ASMR and ASDR of stroke attributable to high temperature were 0.60 (95% UI = 0.07–1.30) and 13.31 (1.40–28.97) per 100,000 population, respectively. The largest burden occurred in Western Sub-Saharan Africa, followed by South Asia, Southeast Asia, and North Africa and the Middle East. ASMR and ASDR increased with age and were higher in males and for intracerebral hemorrhage, and were the highest in the low SDI regions. In 2019, the region with the largest percentage increase in ASMR and ASDR attributable to high temperature was Eastern Sub-Saharan Africa from 1990 to 2019. Conclusions: Stroke burden due to high temperature has been increasing, and a higher burden was observed in people aged 65–75 years, males, and countries with a low SDI. Stroke burden attributable to high temperature constitutes a major global public health concern in the context of global warming.
